Here’s something more for Romans 3:23 thought and prayer. In Mere Christianity, C. S. Lewis (1898–1963) said this about two facts being the foundation of all clear thinking about ourselves:
Human beings, all over the earth, have this curious idea that they ought to behave in a certain way. . . . They do not in fact behave in that way. . . . These two facts are the foundation of all clear thinking about ourselves and the universe we live in.
