We have to repent of our blindness, our lukewarmness, and our disobedience, and turn back to the central truth of Christ as Lord and Saviour; an ethical system will not save us here, nor a timid sentimentalism, nor an excited emotional return, nor a dilettante mysticism. We have to find that deep contrition which is the condition of His abiding. Repentance is not a mere feeling of sorrow or contrition for an act of wrongdoing. The regret I feel when I act impatiently or speak crossly is not repentance. . . . Repentance is contrition for what we are in our fundamental beings, that we are wrong in our deepest roots because our internal government is by Self and not by God. And it is an activity of the whole person. Unless I will to be different, the mind will not follow. True repentance brings an urge to be different, because of the sense of the incessant movement of what I am, forming, forming, forming what I shall be in the years to come.
As we cleanse the inner vessel, there will have to be changes made in our own personal lives, in our families, and in the Church. The proud do not change to improve, but defend their position by rationalizing. Repentance means change, and it takes a humble person to change. But we can do it.

Calamity, war, famine, plague, death, adversity, disease, injury do not necessarily produce repentance. We may become better in a calamity but it does not necessarily make us repent. The essence of repentance is that we cannot be repentant until we confront our own self righteousness with God's righteousness.
