These things write we unto you, that your joy may be full.
I trust to come unto you, and speak face to face, that our joy might be full.
Joy is honoring Jesus, serving Others, and forgetting Yourself. I know a Christian who is always complaining about something in his life that’s not to his liking: he feels sick, or his car has broken again, or he works too hard, etc., etc. Reading the Scriptures, fellowship with others, and listening to the Lord will give us full joy.
