When Calvin says that he would not have spoken of election had Scripture not led the way, we need not doubt his word. If he defends the doctrine with vigour, it is because it runs as an unbroken thread through both Old and New Testaments. Like the doctrines of providence, atonement and the new birth, it is a doctrine of sovereign grace.
Calvin did not invent election: it is a doctrine which belongs to the universal church. Its importance for him lies in the fact that it anchors the work of redemption, not in our feeble powers of will, but in God’s inexplicable love for sinners, and it traces that work to a determination freely made in heaven before the world began.
