New Defender's Study Bible Notes
15:11 joy might be full. The word “fun” is never mentioned in the Bible, and “entertain” is used only in connection with hospitality. Such activities as “reveling” and “playing” only receive condemnation (except for children playing). But the Bible has many references to “joy” and “rejoicing.” Christians have something far better than worldly fun and entertainment. In Christ, they have heavenly joy! See such Scriptures as Jeremiah 15:16; Isaiah 61:10; Philippians 4:4; I Peter 1:8.
