"True gratitude or thankfulness to God for his kindness to us, arises from a foundation laid before, of love to God for what he is in himself; whereas a natural gratitude has no such antecedent foundation. The gracious stirrings of grateful affection to God, for kindness received, always are from a stock of love already in the heart, established in the first place on other grounds, viz. God's own excellency." - Jonathan Edwards, "Religious Affections"
