So intense is the focus on unworthiness that self is on the throne of our life not Jesus. Overcoming Shame is overcome by the grace of God. And the experience of His acceptance begins to heal the sense of rejection that is so prominent in shame. But he gives us more grace. Humility is necessary to fully receive the grace of God.
Pride is a matter of self-centeredness.
The proud think more of themselves and point more to themselves than to Jesus. Shame will cause that. The apostle Paul was a murderer and sworn enemy of Jesus before God's grace touched him. For I am the least of the apostles and do not even deserve to be called an apostle, because I persecuted the church of God. He was humble enough to see reality but by the grace of God was shamed no more.
