The world is depressed. The author really ought to use the Biblical word joy because that is what he means– enduring joy, not just passing pleasure (I Peter 1:8). It is a satisfaction and contentment deep in the soul. Either immediate or future happiness is behind all we do. We must seek it in enjoying and glorifying God. Happiness in self-love? No, because we are never self-sufficient and not designed to be selfishly independent, only God is completely and eternally happy.
Materialism is empty. God’s providential gifts are designed to draw our affections to him. All of creation is designed to tell of the glory of God, not feed the lusts of our flesh. Of course we have needs but all the seeing, hearing, feeling, tasting and smelling are things to enjoy and be thankful for as his gifts. Being ungrateful, and coveting what we don’t have, is idolatry (witness Adam and Eve). The vast majority of sin and crime is caused by this. (James 4:1,2 and subsequently breaking all of the second table of God’s law, the ten commandments).
Christ, the fount of living water is substituted by broken cisterns. Being deprived of spiritual joy necessarily makes people get addicted to physical pleasures (Eccles. 1:8, Proverbs 27:20). Perverse appetites are insatiable. “We must pursue God with all our heart, mind and strength.” We go after fool’s gold…
when Christ must be our supreme treasure. We must deny ourselves and whatever is hindering us to follow Christ (Matthew 16:24). ” Those who find pleasure in God will find pleasure in every situation”-Henry Scougal. This was how Paul and Silas could rejoice in prison. The loss of all we have ought not to diminish our joy. We must relinquish all to follow him….and this is practiclally outworked by believers seeking to belong to a true church where Christ is present-JK. Blessed is the nation (or man) whose God is the Lord (Psalm 33:12).
