God’s purpose of election is bound to be mysterious to men, for we cannot aspire to an understanding of the secret thoughts and decisions of the mind of God. However, the doctrine of election is never introduced in Scripture either to arouse or to baffle our carnal curiosity, but always for a practical purpose. On the one hand, it engenders deep humility and gratitude, for it excludes all boasting. On the other, it brings both peace and assurance, for nothing can quieten our fears for our own stability like the knowledge that our safety depends ultimately not on ourselves but on God’s own purpose of grace.
