Paul said, “All have sinned and fall short of the glory of God” (Rom. 3:23). Sinning is a “falling short” of the glory of God. But the Greek word for “falling short” (husterountai) means “lack.” The idea is not that you shot an arrow at God’s glory and the arrow fell short, but that you could have had it as a treasure, but you don’t. You have chosen something else instead. This is confirmed in Romans 1:23 where people “exchanged the glory of the incorruptible God for an image.” That is the deepest problem with sin: it is a suicidal exchange of infinite value and beauty for some fleeting, inferior substitute. This the great insult.
