Amen, the hardest people to reach are those who have a very high opinion of their self worth. They have not yet reached the truth that they are nothing and Christ is everything. They rage when told they need improvement, even holding deep resentment when corrected or disciplined.
May the Lord convict the stubborn hearts!
Psalm 51:16-17 "…16For You do not delight in sacrifice, otherwise I would give it; You are not pleased with burnt offering. 17The sacrifices of God are a broken spirit; A broken and a contrite heart, O God, You will not despise."
