By Richard Sibbes
Knowledge and affection mutually help one another, it is good to keep up affections of love and delight by all sweet inducements and divine encouragements; for what the heart likes best, the mind studies most. Those that can bring their hearts to delight in Christ know most of his ways. Wisdom loves him that loves her. Love is the best entertainer of truth; and when it is not entertained in the love of it (2nd Thess. 2:10), lovely as it is, it leaves the heart, and will stay no longer. It has been a successful way of corrupting the judgment, to begin by withdrawing love, because as we love, so we tend to judge. And therefore it is hard to be affectionate and wise in earthly things. But in heavenly things, where there has been a right informing of the judgment before, the more our affections grow, the better and clearer our judgments will be, because our affections, though strong, can never rise enough to reach the excellency of the things. We see the martyrs, when the sweet doctrine of Christ had once gained their hearts, it could not be removed again by all the torments the wit of cruelty could devise. If Christ has once possessed the affections, there is no dispossessing of him again. A fire in the heart overcomes all fires without.
