C.S. Lewis read Psalms and wondered why the God of the Bible required His people to praise Him. Does the Lord Almighty possess a big ego that requires constant affirmation? That did not seem plausible to the Cambridge intellectual.
Lewis concluded that God receives unfiltered praise without it making His head swell in pride and that He is truly worthy of all praise. Besides, directing our praise to God keeps us from thinking more highly of ourselves than we should (Romans 12:3).
Thus, it should not surprise us that even the angels of heaven sing repeatedly, “Worthy is the Lamb, who was slain, to receive power and wealth and wisdom and strength and honor and glory and praise!” (Revelation 5:12). If only Lucifer had remained content in the angelic choir.
