The principle of the first is about making sure God is first place in our lives. God called his people to bring the first yield - first fruits - from their harvest to him as an offering. This was to demonstrate the Israelites' obedience and reverence for God. It also showed that they trusted God to provide enough crops to feed their family and we can do the same. Giving God the first tenth of your income "tithe" is just as important. God loves a cheerful giver 2 Cor 9:6-7and a generous one.
