“Repentance means you realize you’re guilty; a vile sinner in the presence of God. That you deserve the wrath and punishment of God, that you’re hell bound. It means that you begin to realize that this thing called sin is in you, and you long to get rid of it, and you turn your back on it in every shape and form. You renounce the world whatever the cost, the world is 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 in 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.”
– Martyn Lloyd-Jones
