Religion consists much in holy affection; but those exercises of affection which are most distinguishing of true religion are these practical exercises. Friendship between earthly friends consists much in affection; but those strong exercises of affection that actually carry them through fire and water for each other are the highest evidences of true friendship.
Jonathan Edwards
Sincere friendship towards God, in all who believe him to be properly an intelligent, willing being, does most apparently, directly, and strongly incline to prayer; and it no less disposes the heart strongly to desire to have our infinitely glorious.
Jonathan Edwards
