"God is love, and he who abides in love abides in God, and God abides in him" (1 John 4:16). In this famous passage, St. John expresses the heart of the Christian faith and the essence of the Christian image of God. In the same verse, he also offers a kind of summary of the Christian life: "We have come to know and to believe in the love God has for us."

In God Is Love, Anthony Kelly, CSSR, takes this phrase as a concise and profound expression and unpacks it for thinking Christians today. He explores seven ideas that are necessarily implied in the love that God is-the Trinitarian terms, Father, Son and Holy Spirit; the cross and resurrection as events within the paschal mystery; the church as the revelation of God's love being worked out in history; and finally, the ultimate hope for eternal life and heaven itself.
