John was the youngest of Jesus’ apostles—likely just a teenager at the time of his calling. And when John came to the twilight of his long life, he wrote down the message that had transformed him. “This is the message we have heard from [Jesus]. . . that God is light, and in him is no darkness at all.”3 Jesus carried to earth the message of God’s complete goodness toward us. God can be trusted. And this message of his goodwill toward us is confirmed by the sacrifice of Jesus on the cross.
