This is hard to wrap your mind around because the church sure will.
But very early in the Bible, we learn of two brothers: Cain and Abel. Both brought an offering to the Lord.
Cain gave what was required out of obligation. Abel carefully searched for the best of his resources to give.
Abel's offering was accepted. Cain's offering was rejected by God.
It's not that God needs your nice stuff. Actually, He doesn't need your stuff at all. He just wants faith.
Giving out of obligation reveals a lack of faith in your giving.
Faith will always move you to give your best and to give what doesn't make sense.
Faith produces unusual generosity.
So, do you believe that God will reward you for giving your best? Because if you do, you would give it all away, with full confidence that God will give you even better.
