Here’s something for Romans 3:23 thought and prayer. In Basic Christianity, John Stott (1921–2011) said this about God’s order and sin’s reversal of it:
God’s order is that we put him first, others next, self last. Sin is the reversal of the order. It is to put ourselves first, our neighbor next, and God somewhere in the background. . . . This basic self-centeredness affects all our behavior.
