“Sing for joy to God our strength” (Psalm 81:4); “The joy of the Lord your strength” (Nehemiah 8:10).
Where does our joy come from? Where does our strength come from? Our joy comes from the Lord. Our strength comes from the Lord. It’s not really our joy and our strength. It’s the joy of the Lord. It’s the strength of the Lord. Everything good in us comes from Him. He puts it into our hearts. We come to Him with our sadness. He gives us His joy. We come to Him in our weakness. He gives us His strength.
