Great Love of God

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."
"By this the love of God was manifested in our case, that God has sent His Only begotten Son into the world so that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be a propitiation for our sins. [...] We have seen and testify that the Father has sent the Son to be the Savior of the world. Whoever confesses that Jesus is the Son of God, God abides in Him, and he in God. We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him." (1 John 4:9,10,14-16)

The fact that God sent His only Son Jesus is proof of God's love for us. God did this of His own prerogative as an expression of His love. Our love, then, is a response to God's love for us.

We can't measure surely the love of God to us.....
