I get the impression for some knowing God is like glue,
Once stuck always stuck - it does not matter what you do or are that is it for eternity.
Now lets look at what Paul says.
To live in the world and be of the world is to be a slave to the passions of the heart.
To live in Christ is to be a slave of love, righteousness.
These are two different worlds driven by different sources and powers.
You are born into both, but can go from the second into the first.
As a baby born into the second you have to learn how to walk in its ways.
It creates a totally different experience. Without washing, cleansing, growing,
sanctification, the changes will not stick or be complete.
The whole basis is the first state is without communion with God, the second
state is about continual communion with God and working this through.
If one rejects the communion with God, you are back to the first state.
