This is a great source of controversy in the churches for the past 2,000 years. Many books have been written on it, many Christians have argued over it, and many churches have been split by it. One needs to apply a basic Christian principle of Biblical Interpretation: Seek answers primarily in the New Testament, and only go to the Old Testament to expand on a truth found in the New Testament. Where the Old Testament disagrees with the New Testament, ignore the Old Testament! In the New Testament, Christians are never told to tithe. This is too important a fact to overlook that nowhere in the New Testament is the believer commanded or urged to tithe. In fact, they are told only to give as they are moved in their hearts to give, a totally free-will type of giving:

2 Corinthians 9:7 “Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.”

True, there is the spiritual truth of sowing and reaping and those who sow sparingly will reap sparingly, but that does not negate the truth that God wants us to give voluntarily. In the Old Testament, there are many scriptures related to tithing. The patriarchs tithed. The Israelites were commanded to tithe. Physical blessings were promised to those who tithed. Tithing is a matter of choice in the freedom we have in Christ. If some want to tithe, and they feel strongly about it, then that is their faith and they should do according to their faith. Likewise, if a Christian only gives when they “feel like it“, that too is good as long as they do it in faith. As Paul said in Romans chapter 14:22-23:

“Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth. And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.”
