Old Testament tithing was just the beginning of giving. In the New Testament, giving is best explained in 1 Corinthians 16:2:
“Give as God has prospered you.”
We often make the mistake of believing that only the first 10% belongs to God, and the rest is ours. Nope, it’s all God’s money. He created it all.
We tithe in recognition of God’s ownership, but if we’re prospering, we should be giving more! After all, giving produces joy.
