Missionary Todd Uhl preached a message about loving God and asks if you truly love God. The key verses of this message are:
Matthew 22:36-38: (36) Master, which is the great commandment in the law? (37) Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. (38) This is the first and great commandment.
Deuteronomy 6:5: And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.
