Tithing: Old Covenant
In the old covenant people gave a certain percentage unto the Lord, whereas in the new covenant we give what God puts on our hearts.
When we go out in faith for Christ, this is when He also does a work in us like no other. Open your mouth and He will fill it.
When Jesus died on the cross, He was the last offering for sin. We can now be forgiven by the blood of Jesus. After sharing this, he agreed upon this.
