“The difference between the ‘before’ and ‘after’ of becoming a Christian is not that before, you sinned, and that after, you are sinless. No – the difference is that before becoming a Christian, sin was in character, it did not really worry you or me. Whereas after becoming a Christian, it is utterly out of character, you do not want to do it. It causes you pain and regret when you do. Not so much because you have let yourself down – although there is that. But because you want to be pleasing Christ – and you have failed him.”
