The centrality of Joy
The joy of the Lord is our strength (Nehemiah 8:10, Prov 17:22),
In his presence there is fullness of joy and pleasures (Psalm 16:11),
Joy is a Fruit of the Spirit (Galatians 5:22)
Joy is not an optional fruit of the Spirit.
To laugh you have to let go of something, e.g. the right to be offended etc.
