As Christians it is good for us to give offerings to our Father to thank him for the gift of life and everything we possess. When giving we should be free from our hearts in order to receive more blessings.
II Corinthians 8:12
Now does God expect someone who is on a very meager income, maybe nothing more than just a little social security check, to give all that to ministry or some church? No way. More than once I've had to write to someone and tell them, "Now listen, if you're on a meager income I don't expect a dime." Now that's between them and God, and if they feel that God is still instructing them to give some then that's fine. But I never want someone on a meager income to feel obligated to support this ministry. Other ministries may not care, but I don't want it on this one. But here God is making it so clear that giving is based on that ability to give."For if there be first a willing mind, it is accepted according to that a man hath, and not according to that he hath not."
