We give because we trust God. Everything we have is already God's, so we trust God with our money and trust Him to provide for and take care of us. God can do more with our 10% than we can do with all 100%.
A tithe of everything from the land, whether grain from the soil or fruit from the trees, belongs to the Lord; it is holy to the Lord.
We give because it is a simple way of showing obedience to God in supporting His mission.
No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money.
We give because we are thankful. Giving is done from a heart of generosity for others as a result of all God has done for us and continues to do in our lives.
Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
2 Corinthians 9:7
