" Jesus said, “These things I have spoken to you, that My joy may remain in you, and that your joy may be full” (John 15:11).The center of joy for the Christian is Christ. The joy is Christ’s joy. It is simply the life of the Lord Jesus Christ being lived out in an individual. Christian joy is letting Christ live His life out through you so that what He is, you become. There are other kinds of joy found in other places in the world, but there is no place where you can find Christian joy except in Christ. "
