Why are you looking at God from a very human centered perspective?
The Fathers of philosophy thought that change was bad and Being was good, so Being did not change. Thus their “God” of Being does not change. The problem with that is beings that are alive change. Those beings, who think and learn, grow and change the most.
Generally humans think that change in the form of growth is good. It says that Jesus grew in wisdom and height, and in favor with God and humans. The issue is that philosophy says categorically that change is bad and no change is good, while theology says that good change is good, and bad change is bad, or no positive change in a evil situation is bad.
I prefer to think that evolution, which is change, is normal and thus is basically good, but we need to guide it in a positive good direction as much as possible. God is in the best position to direct these good changes because God created the universe and knows best how it should work. We are participants, like it or not, because we are part of the universe, so we need to make the best of our lives, which is what God wants for us and everyone else
I really do not know why you seem to be fixated on immature faith. Of course some “Christians” are immature, and they need to pray for maturity. The biggest problem is selfish faith, which is a contradiction in terms. What we need is Christian education, not the condemnation of God as a Person who is able to help people with their most serious problems.
Does God care about the problems of people? YHWH revealed God’s Personal Holy Name, I AM WHO I AM, on the Mountain when YHWH asked Moses to lead God’s people out of slavery in Egypt because YHWH heard their cries for help.
You could also ask God to give the sick comfort in the midst of pain, hope in the midst of darkness. and the faith in the midst of sorrow.
