John 15:11
I have said these things to you so that my joy may be in you, and that your joy may be complete — the goal of Jesus' teaching is not merely information transfer but the transformation of emotion itself: the disciples are invited to share in Jesus' joy, the joy that flows from abiding in the Father's love and accomplishing the Father's work. Complete joy (plērōsis—fullness, completion) is not circumstantial happiness but the deep satisfaction of being aligned with God's purpose, of participating in divine love.
