Michael Harrison (1640-1729) was a faithful Puritan Minister of the Gospel and a powerful Reformed Presbyterian preacher. Harrison concisely teaches the doctrine of justification beginning with Isaiah 45:24-25, “Surely...in the LORD have I righteousness and strength.” He covers, 1. Who are the partakers of this blessed privilege of justification? 2. The nature of justification; what it is. 3. What that righteousness is, for, and by which we are justified. 4. The time when God’s children are made partakers of this blessed privilege. 5. How are we justified by faith? 6. Objections against the doctrine of justification answered. And finally he gives the reader an application. Harrison biblically proves that the righteousness we gain is by the active and passive obedience of Jesus Christ, performed by him in our stead, imputed to us, and received only by faith.
