“How powerful is Satan?”

What kind of power and influence does Satan really have? How do I trust God when I see hospital workers not tending to my mother the way they should? Is God still concerned with the old covenant? How simple is salvation? Do I need to feel assurance for it to be true? What was Israel chosen for specifically? How can I understand the Bible better? So far, I’m having trouble!
