The title is probably the most important question you'll ever answer regarding your eternal destiny. "Whose Son is He?" Jesus is claiming deity! Jesus asked the disciples: "Who do you say that I am?" This is pivotal and your salvation depends upon it. If you don't get your Christology correct, you are lost: "Unless you believe that I AM (with no predicate in the Greek).. you shall die in your sins." John 8:24. That means that Jesus is God Almighty, not a god or made or created God, but eternally God and equal to the Father in essence and being. 2 John 9 says that if anyone does not abide in the doctrine of Christ, he does not have God.... Remember when Peter confessed Christ as the Messiah and Son of the Living God? It is this confession that defines the church of Christ and distinguishes it from cults which twist the passage and make Christ less than He is: fully God in the flesh. The Word became flesh. John 1:14
I am not going to cite all the proof texts of the deity of Christ (e.g., Romans 9:5; Titus 2:13; 1 John 5:20) but it is known that Jesus claimed to be one with the Father (John 10:30) and that the Pharisees understood He was claiming equality with God even if the disciples were dense or clueless for He called God His own Father. (John 5:18). His most famous declaration was John 8:58 where Jesus says, "Before Abraham was, I AM... That is the name of God!
A. W. Tozer said that "the most important thing about is what you think of God!" This shapes our worldview forms our convictions and decides our fate. Do you put God in a box: the doting Grandpa, the Father Time, the Great Spirit in the sky, the Cosmic Killjoy, the Man Upstairs, the Mean Judge, Mother Nature? Note that there are basically four perceptions of God: the benevolent life coach or the one who is immanent and involved favorably, or the critical judge or critic or one distantly involved unfavorably, the authoritative father figure or involved indirectly, or a distant force or impersonal and uninvolved. God is a person we can know, not some force or object or thing we can use. We relate to persons, but use things.
The important thing is that God is not dead and is alive because Jesus rose from the dead "with many infallible proofs." Henry Wadsworth Longfellow said, "God is not dead, nor doth He sleep." The Bible says that the lost are blind and cannot reason themselves to God: "The world by wisdom did not know God." 1 Cor. 1:21 We cannot find God out or fathom Him fully or exhaustively, but we can know Him personally and truly. We come to know God via faith and then we experience or encounter God. All believers have a personal relationship with God; God desires to get personal. We know God by walking in faith and not by sight and learning to walk in the Spirit, cultivating its fruits. Faith is not meant to be a cakewalk, but a challenge and learning experience of a pilgrimage with God. If faith is easy, it isn't worth much, it must be tested! We grow in our faith and in our knowledge of the Lord.
It is not so easy to dismiss Jesus; He is either the Lord, a liar, a lunatic, or a devil. He has not left any other options open according to C. S. Lewis. No one successfully accused Him of sin, much less prove Him a liar; wouldn't His disciples had figured that out? He was so holy that people felt like sinners in His presence like His apostle Peter. His personality has been studied to see if He fits any abnormal profiles and He is the epitome of humanity as our exemplar. The claims He made t be God either make Him a deceiver or devil and liar but you can not say he was just a good teacher for that option isn't open because He plainly claimed to be the Son of God, equal to the Father.
In sum, at the Judgment, all that will matter is what we did with Jesus: salvation is all about knowing Jesus personally (not knowing about Jesus) as one's personal Lord and Savior as Jesus said in His priestly prayer of John 17 in verse 3 that eternal life is know God and His Son! Soli Deo Gloria!
