Creflo Dollar has told his congregation to throw away all his teaching on tithing because he has been wrong in it. Tithing according to what he has found is not mentioned in the NT. I’d already done my research in the past on it and the following is what I found.
I had a 93-year-old preacher tell me one time it was not NT. I searched and found it isn’t in the NT. Only OT. So far as I can tell the NT says give everything. Jesus told the rich man to give all that he had (and went on to promise immense spiritual rewards to those who give everything to follow Him (Matthew 19:29-30). He also commended the widow who gave essentially nothing in actual material value, because she gave “all she had” (Luke 21:4). So, the amount matters not. It’s the “all” part that is correct in giving.
I can confidently say two things on the tithing issue as a biblical matter: (1) the 10 percent tithe was a specific requirement that served a specific purpose under the Old Testament law (see, among other passages, Leviticus 27:32 and Numbers 18:26-32) and (2) neither Jesus nor any New Testament writer assigns or even affirms 10 percent as a specific amount to be given by believers under the new covenant.
But what Christ has done for us on the cross and the future promise of perfect fellowship with God for all eternity has made us free from the old restrictions and requirements of the law, and we are called to present our entire lives as acts of worship to the Lord (see Romans 11:36-12:1). We are subject to giving in a broader sense including our time, talent, and treasure. In the NT we are taught not about tithing, but “giving” out of our abundance. In more than one of his letters, the apostle Paul instructs Christians to give financially — robustly and even sacrificially — to the work of the Gospel, especially toward the preaching of the Word (see, for example, 1 Corinthians 9:3-15, 2 Corinthians 5-9 and 1 Timothy 5:17-18). We should give some thought to what it means to “contribute out of abundance” (Luke 21:4). God is not calling us to irresponsibility.
In that sense, we should “give only what we can,” but as you evaluate that amount. As far as giving all I reference Acts 2:42-46. It’s not about tithing. It’s under the law. The NT under grace says just what the new converts in Acts did. They gave all.
