“You are my Lord; I have no good apart from you” (v2). God is not just one part of life, or a positive addition to other good things; instead, God is the source of Life, the source of good, and our highest authority. Running after idols – anything that competes with God’s place in our hearts - means running away from Life, and it only brings sorrow (v4). The psalmist chose obedience to God over all else: “The Lord is my chosen portion … I bless the Lord who gives me counsel” (v5-7).
“I have a beautiful inheritance … fullness of joy” (v6,11). When we choose to follow Christ above all else, we will not be disappointed in the end.
