Romans 3:9-31 clearly identifies the problem all men face and God’s solution to it. The universal problem of all men is that we all are sinners who have fallen short of the glory of God.
No mere human being has lived a sinless life; in thought, word, and deed, every person has sinned. We have sinned in our understanding, and with our bodies.
No matter what standard of right living we accept or adopt, none of us has perfectly lived up to that standard. In God’s eyes, all the world is guilty of sin.
