Therefore, in a post-Christian world and in an often post-Christian church it is imperative to point out with love where apostasy lies. We must openly discuss with all who will listen, treating all men as fellow men, but we must call apostasy, apostasy. If we do not do that, we are not ready for reformation, revival, and a revolutionary church in the power of the Holy Spirit. We are all too easily infilitrated with relativism and synthesis in our own day. We tend to lack antithesis.
...Francis Schaeffer

Oh! men and brethren, what would this heart feel if I could but believe that there were some among you who would go home and pray for a revival-men whose faith is large enough, and their love fiery enough to lead them from this moment to exercise unceasing intercessions that God would appear among us and do wondrous things here, as in the times of former generations. ...Charles Spurgeon

Revival is a renewed conviction of sin and repentance, followed by an intense desire to live in obedience to God. It is giving up one's will to God in deep humility. ...Charles Finney
