Edward Fisher’s Marrow of Modern Divinity is a classic Reformed text that explains the law, the gospel, justification, faith, and works in great detail. It’s been a blessing for me in my Christian walk and many others have said the same. But it’s not an easy text to read since it is over 300 years old. As I’ve mentioned before, Andy Wilson has recently done the hard work and simplified the Marrow for those who have a tough time with older English. And it’s a good simplification!
Even more recently Wilson has added a new section to his simplification of the Marrow. The part he added is part four which is called, “The Law and the Gospel.” The chapters include rules for properly understanding the 10 Commandments, an exposition of the 10 Commandments, the use of the law, and the difference between the law and the gospel. Here’s an excerpt:
“We are to take heed, when we read the Scriptures, that we do not take the gospel for the law, nor the law for the gospel. Rather, we must labor to discern and distinguish the voice of the one from the voice of the other. The law speaks when any moral work is commanded to be done, either to avoid punishment or to lay hold of a promised reward, whether temporal or eternal, or when any promise is made upon the condition of any work being done.
By way of contrast, wherever the promise of life and salvation is offered to us freely, without any condition or any work done by us, whether we read it in the Old Testament or in the New, this is the voice and doctrine of the gospel.
…The law says, ‘pay me what you owe me, or else I will cast you into prison’ (see Mt. 18:28, 30).
But the gospel says, ‘Christ offered himself up as a ransom for you and so is made redemption for you (see 1 Tim. 2:6, 1 Cor. 1:30).
…The law says, ‘You have not continued in all that I require of you, and therefore you are accursed’ (see Deut. 27:6).
But the gospel says, ‘Christ has redeemed you from the curse of the law, being made a curse for you’ (see Gal. 3:13).
