We are always in a transformative state. Or at least we're supposed to be. God is always wanting to transform us, hence "You are the potter, I am the clay."
We can halt change though.
When you first become a Christian, there's excitement, a desire to know God, a desire to grow and become who God wants you to be.
But at some point that desire can wane.
People get comfortable. Like snuggling up under the covers on a cool night, you bury yourself in bed and don’t want to come out, not even to go to the bathroom because you don’t want to feel the cold air.
In the morning, you have to come out...to go to work, get the kids ready for school or whatever it is that you do.
But in the spiritual life, you don’t have to come from under the covers. You can remain under your comfortable warm blanket. And many believers do after they reach a certain point.
You hit a plateau and spiritual growth stops.
Jonah's a good example (yes, that Jonah).
“I’m not going to Ninevah. I don’t care who’s asking me to do it. I'm not going!”
His attempt at staying under the covers landed him on a boat going as far away from where God told him to go as possible. Then he ends up in the mouth of a huge fish.
And even in the fish’s mouth, it took him three days to pray to God and relent to God’s request. He didn’t want to come out from under his cozy comfortable covers…but God forced him out.
