We should not have so much disputing against the doctrine of election, or hear it condemned (even by good men) as a doctrine of devils. For my own part, I cannot see how true humbleness of mind can be attained without a knowledge of it.
And though I will not say, that everyone who denies election is a bad man, yet I will say . . . it is a very bad sign. Such a one, whoever he be, I think cannot truly know himself. For if we deny election we must, partly at least, glory in ourselves. But our redemption is so ordered that no flesh should glory in the Divine presence. And hence it is, that the pride of man opposes this doctrine because according to this doctrine and no other, 'he that glories, must glory only in the Lord.'
But what shall I say? Election is a mystery that shines with such resplendent brightness that, to make use of the words of one who has drunk deeply of his electing love, it dazzles the weak eyes even of some of God's dear children.--George Whitefield, 'Christ the Believer's Wisdom, Righteousness, Sanctification, and Redemption,' in The Sermons of George Whitefield (Crossway, 2012), 2:214-25
I love Calvinism.
