John G. Reisinger says, “If I were to pick one section of this commentary that gives the heartbeat of both the commentary and of New Covenant Theology, it would be the following:
‘As should be clear by now, love for John is not an emotion but is always practical and active. Love of fellow Christians expresses itself with actions and in truth. Love and obedience go hand in hand. Jesus made this clear in the Upper Room Discourse. John 14:15 says, “If you love me, you will keep my commandments.” In John 14:21, Jesus said that the one who has and keeps his commandments is the one who loves him. John is a faithful interpreter of the mind of Jesus.’”
