You can’t get humanity’s cure right if you get her diagnosis wrong. If you believe people are only psychologically damaged and in need of therapy or only societally oppressed and in need of social justice, you’re missing the deepest problem of the human race and of each individual who has ever lived.
We are sinners.
From 1 John 1: “If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us.”
The blood of Jesus can change and cleanse sinners. That is the only complete solution to the ultimate problem of people.
