"The best saint when he looks at himself becomes unhappy; he sees things that should not be there, and if you and I spend our whole time looking at ourselves we shall remain in misery, and we shall lose the joy. Self-examination is alright, but introspection is bad. Let us draw the distinction between these two things. We can examine ourselves in light of Scripture, and if we do that we shall be driven to Christ. But with introspection a man looks at himself and continues to do so, and refuses to be happy until he gets rid of the imperfections that are still there. Oh, the tragedy that we should spend our lives looking at ourselves instead of looking at Him who can set us free!"
- D. Martyn Lloyd-Jones
