The pagan Emperor Trajan once asked a Christian why his God was invisible and you couldn't see him (it sounded atheistic to him--just worshiping a spirit), and he was informed and given the scoop: "Look at the sun!" Trajan said he couldn't because it's too bright. "Then don't you now realize that, if you cannot behold God's creation, how much less the splendor and glory of God?" Jesus said that God is Spirit and those who worship Him must worship in spirit and in truth (cf. John 4:24).
The Greek believers asked the disciples if they could see Jesus. "We would see Jesus!" We don't need to see Him in order to know Him, because Jesus said blessed is he who believes and hasn't seen (cf. John 20:29). We can see with the eyes of our hearts which are opened by the Holy Spirit's illuminating ministry. We are seeing the glory of God when our eyes are opened to see how He is manifest in believers, and we see Jesus in them and they see Him in us--this is only a taste of the glory which shall be revealed to us. As Hebrews 2:9 (ESV) says: "But we see him [i.e., Jesus, with our spiritual eyes] ...."
We shall all be satisfied in heaven by beholding the face of God (in Jesus), but only because we will not be in the flesh, but without any sin to corrupt our spiritual bodies and souls. God has revealed Himself throughout the Bible in many theophanies (revelation of God, such as in the burning bush) and Christophanies (revelation of Jesus, such as the Angel of the LORD). From the burning bush to appearances as the Angel of the LORD, to Gideon and as the Son of Man, to Daniel's friends in the furnace, and to Daniel in a vision. John saw Jesus in His glory at the transfiguration and then finally at Patmos in a vision of heaven.
Jesus is how God manifests Himself as the embodiment, personification, or icon of God. When Philip (cf. John 14:8-9) asked Jesus during the Last Supper in the Upper Room to show them the Father, Christ said, that he who has seen Him has seen the Father--they are one! All that God wants to reveal of Himself is presented in the Son--all that God has to say to us and all that we can know. God is Spirit, according to Jesus, and became a man for our sake so we would have something to relate to and what to think of when we meditate on God. Jesus is analogous to the sun because He gives light to all He shines on, and makes life possible too.
Jesus has the Shekinah (glory of God), not reflected the glory of God, as Moses had after being in His presence. Jesus does not reflect light--He is light: John 8:12 says, "... I am the light of the world...." Jesus willingly veiled His glory because they couldn't behold it in full. Jesus has all the glory of the Father, there is no diminishing of it, but He voluntarily laid it aside (known as the kenosis in Philippians 2) while incarnated on earth before His ascension. Actually, Jesus shines brighter than the sun, which is only an analogy or symbol of Him.
In glory, we shall behold Him: "... [B]ut we know that when he appears we shall be like him because we shall see him as he [Jesus]" (1 John 3:2, ESV). Moses wanted to see God's face but God said that no man shall see His face and live [in the flesh], as Jesus told Moses in Exodus 33:23. Jesus said in His Beatitudes that the pure in heart are blessed, for they shall see God [in the NT God usually refers to God the Father].
Don't forget the Aaronic benediction in Numbers 6:24-26 as a promise to claim: "The LORD bless you and keep you; the LORD make his face to shine upon you and be gracious to you, the LORD lift up his countenance upon you and give you peace." What man has always yearned for is a God they can see; one that has skin on and we can relate to. Jesus is just that incarnation: God with skin on!
Jesus said that "God is glorified in Him" (cf. John 10:34) and this is when He is glorified. At His priestly prayer in John 17 Jesus besought the return of His glory after He had glorified the Father by doing all His will and being obedient in His subordination and humility. He did it by accomplishing all God's work for Him on earth that was given Him to do (cf. John 17:4). By analogy we give up our glory to share His glory and to glorify God: "The chief end of man is to glorify God, and enjoy Him forever" (The Westminster Shorter Catechism, ca. 1646).
Everyone will bow to the glory of God, either at Judgment Day, or to become a believer and surrender the control over himself, and even others, to the lordship of Christ. We must give up the ownership of our lives and realize we owe all to Him because He purchased us at the cross with His blood. But Jesus wants more than our bodies dedicated to Him as reasonable service (cf. Rom. 12:1), He wants us (to surrender everything we have and are to His lordship)! This entails and involves giving up your personal throne and kingdom and surrender it to God's sovereignty and guidance or plan for your life--we don't ask God to bless our plans, but Him to reveal His plan.
We leave our throne to bow to His and ultimately get a crown to reign with Him, just like Jesus left His throne in Heaven to humble Himself in obedience all the way to the cross. This surrender and acknowledgment of His lordship are not only done at salvation but renewed daily, as we learn to walk in the Spirit and in fellowship with God and our brethren (cf. 1 John 1:7). We actually have more authority in Christ after surrendering our authority and this is a paradox indeed (i.e., if we are lords, we are to become servants for Christ's sake and humble and meek enough that no service is beneath our dignity). We have nothing in comparison to lose and everything in eternity to gain, including the right to rule in glory with Christ, as we go from glory to glory to an ultimate glorified state in the New Jerusalem.
He doesn't want sacrifice or offering, or even going through the motions of the rituals of worship--Jesus internalized religion to make it a matter of the heart (He said evil comes out from the heart of man) because the Pharisees had externalized it to outward obedience to the letter of the Law, and neglect of the spirit of the Law. He wants all there is of us--all of our minds, hearts, souls, spirits, strength, and wills. John was stunned at the sight of the Lord, so just imagine how we would react!
Jesus is the Great Inspector General of the church and we all need to pass muster and be ready for daily inspection of our daily walk--take regular spiritual check-ups so as not to jeopardize your testimony to the world. Paul said to "test yourselves whether you are in the faith." We are to examine ourselves (cf. 2 Cor. 13:5)--not others--regularly and especially before the Lord's Supper. We are fruit inspectors--not detectives. We must examine ourselves first because judgment begins at the house of God, and when we have cast the beam out of our own eye we can help someone else with the speck in theirs.
In other words, don't throw bricks if you live in a glasshouse, because we all have feet of clay or have vulnerabilities not readily apparent--we may see the sins of others as obvious; however, we just sin differently and have no right to look down on our brother or criticize him, and we are all vulnerable to Satan's attack, which Martin Luther called the Anfectung, and we should never succumb to this nor even his accusations. If we take care of our witness and testimony, God will take care of our reputation and open doors for us--we must just be ready!
Men have always imagined what God must be like and Christians have longed to see visions and revelations of God, known as theophanies. But no one knows what God looks like because God is Spirit (cf. John 4:24)! Moses saw the backside of the glory of Christ, who does reveal Himself, but the Father doesn't and no man has ever seen the Father. Our faith concerns the God who is there!
A child was asked what he was drawing in class: "I'm drawing a picture of God!" The teacher told him no one knows that: the child said, "They will now." The child had to learn that no one can draw God, but the child answered that people will see now what He looks like. Children have an innocent faith and we are to mimic it (cf. Matt. 18:3). Hebrews says that we do see Jesus (cf. Heb. 2:9), and we sense His presence when two or three are gathered in His name as a promise (cf. Matt. 18:20).
He indwells each of us and we can have an existential encounter with Him as we read Scripture, fellowship, worship, or pray. Christians see the glory of God in His work on earth and will see God's glory in heaven, to our delight. The prophets who claimed they "saw God" were seeing theophanies, and not God in His fullness. We cannot bear to look at the sun in its brightness, much less look at the glory of God directly. That's one reason God reveals Himself propositionally and in the Word.
Christians want Christ to be seen in them and also to seek Christ being glorified. As Paul said in Col. 1:27, "Christ in you, the hope of glory." He also boasted that Christ was glorified in him. We wait till Christ be formed in us and in our brethren as a sign of maturity. God will never give up making us in His image and we are works in progress (cf. Phil. 1:6).
The Greek disciples who came to the apostles and said they "[wanted] to see Jesus"; we have a much greater thing in that we have the Word of God and full revelation of the wisdom and knowledge of God in it--we're better off than being with Christ in person also because we have the inner blessing of the Spirit. The apostles said that it would suffice to see the Father, but Jesus said that to see Him was to see the Father! All that we can know and see God is revealed in Christ! In eternity we'll see the big picture!
The infidel doesn't see God anywhere at work, but the believer sees His fingerprint everywhere, from the smallest atom to the largest galaxy, at work. No amount of proof will convince someone who doesn't want to do God's will or sincerely have a relationship with him; to the believer and honest seeker, there is ample evidence--no one can disbelieve due to lack of evidence!
In glory, we shall behold Christ as He is and we shall be like Him too, able to take it in. It is said that some angels always do behold the face of God and that Gabriel "[stands] in the presence of God"; we'll have more privilege than an angel! People generally say that seeing is believing; however, believing is seeing! Don't envy those who have seen a vision or revelation, as Jesus told Thomas: "Blessed are those who have not seen, and yet believed" (cf. John 20:29). Jesus rebuked the Pharisees who maintained they could see but were "blind guides," in fact, the "blind leading the blind"; think how much worse it is to think you see and be blind, or not knowing you're blind! Christ came to open our eyes and to make the blind see, and Satan has blinded the eyes of all who don't believe in Christ (cf. 2 Cor. 4:4).
Caveat: Don't reduce God to one dimension or put Him in a box, emphasizing one aspect, like seeing Him just as: the Old, Doting Grandpa who says, "Boys will be boys;" the Kind Father; the Man Upstairs; Cosmic Killjoy; the Great Spirit; the Strict, Mean Judge; the Higher Power; or even as the Great Mathematical Mind. Whenever we have an inadequate perception of God it's idolatry and our God is too small, thinking of Him in human terms. How big is your God, is just as important as seeing Him. God cannot be limited, defined, or confined, and we must know that He is beyond comprehension, known as His profundity, and we will never fully apprehend His glory, nature, or essence throughout eternity ("the finite cannot contain the infinite," says the maxim).
The eyes of our hearts are opened upon salvation and we can literally say we see and were blind, just like the blind man Jesus healed said, "I was blind, but now I see!" No one can argue the fact that we have spiritual eyes enlightened and illuminated by the Holy Spirit living in our hearts. Theologians have attempted definitions of God in vain, for He cannot be described, only known, loved, and worshiped!
It is the childish faith that seeks to know God through pictures, visions, or experiences, but the mature obedient believer clings to the Word and hears God speaking His message through it; just like Francis Schaeffer wrote: "He is there, and He is not silent!" The problem with man is not only is he blind to spiritual truth, but spiritually hard-of-hearing and turns a deaf ear to the gospel message that he does hear. Man isn't faithful to the God he does see and is without excuse. Soli Deo Gloria!
