Forgiveness is just another word for loving the real person rather than our idealised image.
Humility is accepting that both evil and an omnipotent, loving, good God are real.
It has taken my working through over a hundred psalms to truly understand that God is not changeable – it is our perceptions of God and our feelings about God that are changeable. The psalmists live through storms of despair and doubt and feeling that God is angry and has abandoned them but return again and again to the calm climate of joy and praise.
