Salvation is a rescue operation. To understand salvation, we need to know what the problem was, what God did about it, and how we respond to it.
When God made humans, he made them "in his own image" (Genesis 1:26-27). We are in some way like God himself. That’s because God has something special in mind for us.
But as we all know, humans can be rather ungodly as well. Humans are noble and crude at the same time. We can have high ideals, and yet be barbaric.
