Does a Christian have to tithe?
A New Testament teaching on giving which may be helpful to you is found in 1 Corinthians 16:2:
“On the first day of every week, each one of you should set aside a sum of money in keeping with his income.”
This passage brings out four points: we should give individually, regularly, methodically and proportionately.
The matter of your giving is between you and God, and He always takes into account our circumstances. He knows when they are beyond our power to direct and control. The important thing is that we see giving as a privilege and not a burden. It should not be out of a sense of duty, but rather out of love for the Lord and a desire to see His kingdom advanced.
Second Corinthians 9:6-7 says: “Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.”
The deeper question, you see, is this: What has priority in our lives? Is Christ really first—or do we put ourselves and our own desires first? Make sure Christ is first in your life, and then ask Him to guide you.
