"We put our common sense on the throne and then attach God's name to it." ~Oswald Chambers
Those truths can become common sense, and we begin to uplift the good ideas that happen to coincide with Jesus' teachings and things that he might say. However, that common sense and those inspirational ideas become the idol and they get in the way of worshiping God. If they cannot simply be a step, a reinforcement to be pocketed but not dwelt upon, then they are most likely going to become a sort of god, or at least making God become his moral standards rather than what he is: the ultimate, perfect and holy being who created those standards to keep us in our place.
"In essence, Jesus says, 'Continue steadily on with what I have told you to do, and I will guard your life. If you try to guard it yourself, you remove yourself from My deliverance.' Even the most devout among us become atheistic in this regard--we do not believe Him." ~Oswald Chambers again
