I cannot close this chapter without noticing, in connection, a passage in the book of Deuteronomy which may present a difficulty to some minds. It has direct reference to the subject on which we have been dwelling. "And the Lord heard the voice of your words, when ye spake unto me; and the Lord said unto me, 'I have heard the voice of the words of this people, which they have spoken unto thee: _they have well said all that they have spoken_.'" (Deut. v. 28.) From this passage it might seem as though the Lord approved of their making a vow; but if my reader will take the trouble of reading the entire context, from verse twenty-four to twenty-seven, he will see at once that it has nothing whatever to say to the vow, but that it contains the expression of their terror at the consequences of their vow. They were not able to endure that which was commanded. "If" said they, "we hear the voice of the Lord our God any more, then we shall die. For who is there of all flesh that hath heard the voice of the living God speaking out of the midst of the fire, as we have, and lived? Go thou near, and hear all that the Lord our God shall say; and speak thou unto us all that the Lord our God shall speak unto thee, and we will hear it and do it." It was the confession of their own inability to encounter Jehovah in that awful aspect which their proud legality had led Him to assume. It is impossible that the Lord could ever commend an abandonment of free and changeless grace for a sandy foundation of "works of law." CHAPTER XX. It is of the utmost importance to understand the true character and object of the moral law, as set forth in this chapter. There is a tendency in the mind to confound the principles of law and grace, so that neither the one nor the other can be rightly understood. Law is shorn of its stern and unbending majesty, and grace is robbed of all its divine attractions. God's holy claims remain unanswered, and the sinner's deep and manifold necessities remain unreached, by the anomalous system framed by those who attempt to mingle law and grace. In point of fact, they can never be made to coalesce, for they are as distinct as any two things can be. Law sets forth what man ought to be, grace exhibits what God is. How can these ever be wrought up into one system? How can the sinner ever be saved by a system made up of half law, half grace? Impossible. It must be either the one or the other.
