“The righteous will flourish like a green leaf” (v28). God is self-giving, loving, and generous, and our lives flourish when we act like His children. We can “give freely” without fear, because God is generous (v24), and we can pour ourselves out for others because He will always refresh our souls (v25). We don’t have to be perfect, but we can commit ourselves to God’s kingdom, desiring it and investing in it now by faith, and know that our efforts will end in good (v23,27).
“The fruit of the righteous is a tree of life” (v30). When we are living at peace with God, we become like fruit-producing trees, spreading life to others.
