The Necessity of Religious Affections

I am bold in saying this, but I believe that no one is ever changed, either by doctrine, by hearing the Word, or by the preaching or teaching of another, unless the affections are moved by these things.  No one ever seeks salvation, no one ever cries for wisdom, no one ever wrestles with God, no one ever kneels in prayer or flees from sin with a heart that remains unaffected.  In a word, there is never any great achievement by the things of religion without a heart deeply affected by those things.

Jonathan Edwards, Religious Affections
