It sounds like George MacDonald wanted glory for himself. But Jesus said:
I am not seeking glory for myself; but there is one who seeks it, and he is the judge. ~~ John 8:50
God gives us a glory when we don’t seek it for ourselves. We seek the glory of God. God isn’t selfish for seeking His glory for He is the greatest most glorious being in the universe. Moreover, in seeking His glory He breaks the bondage to the idol of self in His creatures. Therefore this is an act of love on God’s part. Not selfishness. He knows we won’t be complete until we give Him the glory. The glory the creature receives is in humility. In giving God the glory we receive a glory. We keep it by giving it away. My main motive for loving and being kind to others is to glorify God.
When we seek our own glory (self-esteem) we become aggressive bullying and egotistical. George MacDonald was verbally abusive to people (Calvinists) and he hated God because of His wrath. George MacDonald didn’t love his enemies. But Jesus did and he commanded us to. This is what happens when you seek your own glory. It leads to ego. For me it even lead to megalomania. This is from my book called “The Wisdom To Know the Difference” by the psychologist and professor of psychology at the University of Mississippi. It’s under the section called “The Self-Esteem Myth”
