1 John 4:8-10

The one who does not love has not become acquainted with God [does not and never did know Him], for God is love. [He is the originator of love, and it is an enduring attribute of His nature.] By this the love of God was displayed in us, in that God has sent His [One and] only begotten Son [the One who is truly unique, the only One of His kind] 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 the propitiation [that is, the atoning sacrifice, and the satisfying offering] for our sins [fulfilling God’s requirement for justice against sin and placating His wrath].
