The Cause of Legalism and Control

I've been reading Ryan Rufus's awesome new book; "Sanctification by Grace". Here's a quote;

"I believe that the cause of so much of the legalism and control in the church today comes from a failure in "seeing our salvation". If you haven't seen your salvation then you haven't seen that your spirit has been made perfect and complete in Christ and that nothing else needs to take place.

Unfortunately many haven't seen that so they're busy trying to complete their salvation. They're trying to complete their righteousness, complete their holiness, complete their death to self, complete their worthiness to receive blessings from the Father, complete their right to come boldly before God.

Many Christians are confused about this. They think we still have a sinful nature and are under the law! So they are trying to control something they don't have, by using something they are no longer under. In other words they are trying to control (or die to) a sinful nature they don't have by using God's law that they are no longer under! That is called sanctification by law and it is totally weak and useless".

Let me repeat that. They are trying to control (or die to) a sinful nature that they don't have by using God's law that they are no longer under. Afraid that grace will lead to licence? Oh give over. You're sinning already one way or another. What have you got to lose?
