It is very easy to grieve the Spirit of God; we do it by despising the discipline of the Lord, or by becoming discouraged when He rebukes us. If our experience of being set apart from sin and being made holy through the process of sanctification is still very shallow, we tend to mistake the reality of God for something else. And when the Spirit of God gives us a sense of warning or restraint, we are apt to say mistakenly, “Oh, that must be from the devil.”
