All Christians don't keep his commandments.
Here is an example of what Washer says:

Go back and do a search on worldliness and other related topics.
What we should watch on TV?
What kind of jokes we should or should not tell?
What kind of clothes we should wear--no pants or jeans on women--only skirts and dresses below the knees. Right?
What our talk should be like; our conversation?
What our behavior should be like--places we should go to or avoid?
The music we should listen--CCM come to mind?
And most of all agree what is called "worldiness" I am sure that we all agree on this. Right.
If you don't agree with Washer; if you fit into these categories; then friend you are not saved, even if you did ask "Jesus into your heart."
And that is not Scriptural.
