We need a Savoir.
Acts 4:12, "Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved."
What can man do to appease the wrath of God, to atone for all our sin, to escape the punishment so justly deserved? Nothing you do will in any way make amends to God for even one evil work, word or thought. If you could from now on do all things well and perform perfect, uninterrupted obedience, it would not atone for what is past. Not increasing your debt would not discharge it.
But suppose perfect obedience from this day forward could atone for the sins that are past; this would be of no profit, for you are not able to perform it in any point. Begin now to make the trial. Shake off the outward sin which constantly besets you. You cannot. How then will you change your entire life from all evil to all good? Indeed, it is impossible unless your heart first be changed.
And are you able to change your own heart from all sin to all holiness? No more than you are able to give life to a dead body and raise one who lies in the grave. You can do nothing in this matter; you are utterly without strength.
To be deeply sensible of this, how helpless you are ---- as well as how guilty and how sinful ---- is that repentance which is the forerunner of the Kingdom of God. One step more, and you will enter in. You do repent. Now, believe the gospel.
