I love these which I saw earlier today on another blog...
"God never clothes men until He has first stripped them, nor does He quicken them by the gospel till first they are slain by the Law. When you meet with persons in whom there is no trace of conviction of sin, you may be quite sure that they have not been wrought upon by the Holy Spirit; for ‘when He is come, He will reprove the world of sin, and of righteousness, and of judgment.’"
"I would not give a penny for your love of truth if it is not accompanied with a hearty hatred of error."
- C.H. Spurgeon
