Let those who delight in my righteousness shout for joy and be glad and say evermore, “Great is the LORD, who delights in the welfare of his servant!” (Ps 35:27, ESV)
The Hebrew word for welfare in this verse, shalom, also refers to completeness, peace, tranquility, and contentment. Many seek after these things in life, and we often think that it is for our own good. But it turns out that God is also delighted when we are well and at peace.
