The phrase ‘God is love’ comes from 1 John and is used to convey many different ideas of who God is. But ‘God is love’ is not the only ‘God is’ in 1 John—it also says that ‘God is light’. In the book of 1 John, John proclaims who God is in light of the revelation of Jesus. After the Resurrection, the disciples truly saw that Jesus was the central revelation of God’s character and spent the rest of their lives proclaiming that revelation. In the book of 1 John, John testifies to what they saw in Jesus, that God is light and love.
