“John says the end of the change process is certain: I will be like Jesus when I see him as he is (1 John 3:2). That means changes is not only possible, it’s inevitable!
I used to think that sanctification was a bit like pushing a boulder up a hill. It was hard, slow work, and if you lost concentration you might find yourself back at the bottom. But it’s more like a boulder rolling down a hill. There’s something inevitable about it, because it’s God’s work, and God always succeeds. The sad thing is that often I try to push the boulder back up the hill. I say in effect, ‘Don’t change me yet–I like doing that sin.'”
