Here is a summary of the doctrine of the gospel concerning the great work of our redemption by Christ. It comes in here not as the matter of a sermon, but as the matter of a thanksgiving. He does not discourse of the work of redemption in the natural order of it; for then he would speak of the purchase of it first, and afterwards of the application of it. But here he inverts the order, because, in our sense and feeling of it, the application goes before the purchase. We first find the benefits of redemption in our hearts, and then are led by those streams to the source.
