Repentance means that you realize that you are a guilty, vile sinner in the presence of God, that you deserve the wrath and punishment of God, that you are hell-bound. It means that you begin to realize that this thing called sin is in you, that you long to get rid of it, and that you turn your back on it in every shape and form. You renounce the world whatever the cost, the world in its mind and outlook as well as its practice, and you deny yourself, and take up the cross and go after Christ. Your nearest and dearest, and the whole world, may call you a fool, or say you have religious mania. You may have to suffer financially, but it makes no difference. That is repentance.
