Question:
Why should we love God and where do we read about our love for God?

Answer:

Deuteronomy 6:5: “You shall love the Lord your God with all your heart and with all your soul and with all your might.” The Lord should come first in our life just as He put us before Himself.

Verses that were given as to why we should love God were:  Psalm 139:14: “I will give thanks to You, for I am fearfully and wonderfully made; Wonderful are Your works,” and John  3:16: “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.”   Some reasons that we should love the Lord are because He made us, and He gave His Son to die for us.  The ultimate reason that we should love the Lord is 1 John 4:19: “We love, because He first loved us.”
