"Few words used in the Bible can claim to be
misunderstood as much as the word "love." It is essential in our
understanding of what God feels toward us and how He acts for us. In
this passage, John the Apostle writes to us with a staggeringly
important truth about both God and love: "God is love." How do we
make sense of the love of God? John directs us to Jesus: we can't
understand love without understanding atonement. There is no love
without atonement; no Christmas without the cross. It was because
of the love of God that Jesus came, and that same love sent Him to
the cross so that we could both receive and experience love."
