One of life’s most important decisions is which philosophy to live by. This will have far-reaching consequences (not all of them foreseeable). David has made his own choice of which god to serve: “I say to the LORD, ‘You are my Lord.’” (verse 2) And he commits himself to God’s care and protection (verse 1). He relies on God alone for security, and looks nowhere else for happiness. And because he loves God, he has a close affinity with others who have a similar love for God (verse 3). In the same way, Christians share a bond with all other Christians (whatever their ethnicity or denominational affiliation).
What alternatives are there? Man-made religions demand much effort and give little reward. Yet idolatry is the ‘default option’ of the world, and it exerts an almost irresistible pull on us. Hence the repeated warnings against it in both Old and New Testaments (e.g. Joshua 23:7,8; I Corinthians 10:14). Conversion is not just a once-in-a-lifetime event; it has to be consciously and consistently worked out in our daily lives as we maintain our allegiance to the living God.
Such loyalty is not without cost – but it also has its reward. “Do not be afraid, little flock, for your Father has been pleased to give you the Kingdom.” (Luke 12:32) David has found a greater satisfaction in his God than in the uncertainties of this world (verses 5,6). The person who has God possesses everything they need; they do not need to seek security in material things. Our wealth is unseen, but not unreal; it is intangible, but not insecure. “Praise be to the God and Father of our Lord Jesus Christ! In His great mercy He has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that can never perish, spoil or fade.” (I Peter 1:3,4)
