Paul changes the metaphor to taking off clothing and putting it on. Is it possible that, just by thinking about it, the clothing we now wear will just fall off? We must make an effort to disrobe. On the other hand, we have to choose what clothing we will wear in its place. Then we have to make the effort to put it on.

These things are so clear. Do we see that we cannot just stand still? Growth, in terms of salvation, is not something that just happens because we receive the Spirit of God. It is caused to happen.
