That he loves us in spite of the fact that we do nothing he can really be proud of, is the greatest story of all.
Isaiah 64:6 All of us have become like one who is unclean, and all our righteous acts are like filthy rags; we all shrivel up like a leaf, and like the wind our sins sweep us away.
Acts3:20 "Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin."
My guess is... well, according to the Bible... that it is not his individual acts or individual transgressions which please or displease God, but his faith.
Hebrews 11:6 " And without faith it is impossible to please God"
Your assertion that God is "not proud of someone" because of something one said, is completely unBiblical and inaccurate. God may or may not be PLEASED with something someone says, but God is never proud of us one way or another, at least, I can't find anything to support that idea.
It's kind of like trying to say God is vain because he says in his word he is the only one worthy of praise. Surely if a human said something similar we might consider it vain. But God? Likewise with pride. You may feel this is a semantic argument. But when you consider pride is one of the 'seven deadly sins' I would say you ought to use caution ascribing pride to God.
