"The word of God, which is given for our instruction in divinity, contains enough in it to employ us to the end of our lives, and then we shall leave enough uninvestigated to employ the heads of the ablest divines to the end of the world. The psalmist found an end to the things that are human; but he could never find an end to what is contained in the word of God: Psal. cxix. 96. " I have seen an end to all perfection; but thy command is exceeding broad." There is enough in this divine science to employ the understandings of saints and angels to all eternity."
- Jonathan Edwards, from his sermon: Christian Knowledge
