Ever hear of the phrase "he who dies with the most toys wins?" We have become a materialistic society that is trying to serve money, or mammon, as Jesus called it; he also said you cannot serve God and mammon. We are to be content with what we have and not to covet: it was this command that convicted Paul of sin. Sinners use people and love things; the godly use things (to God's glory) and love people. Billy Graham cites a man who says that it is not the abundance of our possessions that makes us rich, but the fewness of our wants. "The LORD is my shepherd, I shall not be in want...." A. W. Tozer, in The Pursuit of God, says that there is a blessedness in possessing nothing: when we possess nothing (i.e., claim exclusive rights to and see things as "mine" and "my" instead of God's in the vein of selfishness), then we own all. In Obadiah God says that Israel "shall possess its possessions." Corrie ten Boom says to "hold all things loosely." We are only stewards: God actually owns everything we are using for His glory.
This life is only a staging ground to prepare for eternity and blessings are only God's way of testing us. "Blessed are the poor in spirit, for theirs is the kingdom of God." The poor usually have a better attitude toward riches and often enjoy the little things of life more than the rich: there are those who are rich, with everything to live on, and nothing to live for. I recall The Beatles' song that goes, "I don't care too much for money; money can't buy me, love." There is an abundance of blessings that money cannot buy and these are the best things in life. Money can buy food, but not appetite and time, but not leisure, and a bed, but not sleep. Blessings come only from God. Sometimes it is a curse to get everything we want, because we may not get the ability to enjoy it, like the rich man who had laid up treasures for himself and didn't realize that that day his soul would be required of him.
God has chosen the poor in this world to be rich in faith, and the rich and poor have this in common: "God is the maker of them both." The song goes, "As rich as you are, it is better by far, to be young at heart." Paul emphasized contentment and said that he would be content to have food and clothing. Hebrews 13:5 says to be "content with what you have." The desire for things and money can buy a lot of things, never can be satisfied; we don't want to get caught up in this never-ending rat race if you will--even if you win, you're still a rat (acc. to Lily Tomlin).
However, on the positive side, God has given us all things to enjoy (cf. 1 Tim. 6:10), and there is nothing inherently wrong with things but only when they keep us from putting God first. Having too much of the devil's delicacies can keep us from having an appetite for heavenly things though.
Try to see things in light of eternity and stewardship, and not become too secure ("Woe to those who are at ease in Zion" cf. Amos 6:1)) in our thinking that God can't take away, as surely as He can bless: I have been there and the song goes: "You don't know what you've got, till it's gone." Job said, "The Lord gives, the Lord has taken away; blessed be the name of the Lord." You don't really know that Christ is all you need until Christ is all you have, you might say. Billy Graham says it well when he tells of a rich man who came to him and said he had everything to live on, and nothing to live for.
The key is that we own naught: "The earth is the Lord's, and the fullness thereof." It is not how much of our money we give to God, but how much of God's money we keep for our stewardship to His glory." Remember, "For where your treasure is, there your heart shall be also," (cf. Matt. 6:21) Soli Deo Gloria!
