1 Peter 1:22-2:3 highlights how the gospel creates new people, with new loves and new appetites. This transformation happens as the grace of God which saves us is the same grace that grows us. The love of God which flows out of new hearts is pure, sincere, earnest, and heartfelt. As we put on love, we must put off self-serving attitudes and anything that would hinder our love for our brothers and sisters.
