Is this contrition the same as repentance or not? The description of repentance in the sections below will enable you to conclude that repentance is not possible unless we know not only in a general way but also in specific detail that we are sinners. This is something we cannot know unless we examine ourselves, see the sins that are within us, and condemn ourselves on their account.
The contrition that preachers say is necessary to our faith has nothing in common with the actions just listed. It is only a thought and a confession that we have been born into the sin of Adam and into an inclination toward the evils that spring from that sin, and that therefore the wrath of God is upon us and we deserve damnation, destruction, and eternal death. Clearly, then, this contrition is not the same as repentance.
