Repentance

… I sent up these sorrowful words: How long, how long, "tomorrow, and tomorrow?" Why not now? why not is there this hour an end to my uncleanness?

These things, beloved, we write unto you, not merely to admonish you of your duty, but also to remind ourselves. For we are struggling on the same arena, and the same conflict is assigned to both of us. Wherefore let us give up vain and fruitless cares, and approach to the glorious and venerable rule of our holy calling. Let us attend to what is good, pleasing, and acceptable in the sight of Him who formed us. Let us look stedfastly to the blood of Christ, and see how precious that blood is to God, which, having been shed for our salvation, has set the grace of repentance before the whole world. Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him. Noah preached repentance, and as many as listened to him were saved. …

16. And forgive us our debts as we also forgive our debtors. For we have many sins. For we offend both in word and in thought, and very many things we do worthy of condemnation; and if we say that we have no sin, we lie, as John says. And we make a covenant with God, entreating Him to forgive us our sins, as we also forgive our neighbours their debts. Considering then what we receive and in return for what, let us not put off nor delay to forgive one another. The offences committed against us are slight and trivial, and easily settled; but those which we have committed against God are great, and need such mercy as His only is. Take heed therefore, lest for the slight and trivial sins against thee thou shut out for thyself forgiveness from God for thy very grievous sins.

Repentance is the returning from the unnatural into the natural state, from the devil to God, through discipline and effort.
