Charles Spurgeon Commentary Deuteronomy 6:15-19

"for Jehovah thy God in the midst of thee is a jealous God; lest the anger of Jehovah thy God be kindled against thee, and he destroy thee from off the face of the earth. Ye shall not tempt Jehovah your God, as ye tempted him in Massah. Ye shall diligently keep the commandments of Jehovah your God, and his testimonies, and his statutes, which he hath commanded thee. And thou shalt do that which is right and good in the sight of Jehovah; that it may be well with thee, and that thou mayest go in and possess the good land which Jehovah sware unto thy fathers, to thrust out all thine enemies from before thee, as Jehovah hath spoken." — Deuteronomy 6:15-19 (ASV)

Lest the anger of the LORD thy God be kindled against thee, and destroy thee from off the face of the earth. Ye shall not tempt the LORD your God, as ye tempted him in Massah. Ye shall diligently keep the commandments of the LORD your God, and his testimonies, and his statutes, which he hath commanded thee. And thou shalt do that which is right and good in the sight of the LORD: that it may be well with thee, and that thou mayest go in and possess the good land which the LORD sware unto thy fathers, To cast out all thine enemies from before thee, as the LORD hath spoken.

Now, this covenant of works they break, as we also have long ago broken ours. Blessed be God, our salvation now hangs on another covenant which cannot fail nor break down – the covenant of grace.

Yet, now that we become the Lord's children, we are put under the discipline of the Lord's house. These words might not unsuitably describe what the discipline of the Lord's house is towards His own children: namely, that He blesses us when we walk in His ways, and He will walk contrary to us if we walk contrary to Him. He keeps a rod in His house, and in love He uses it on His most beloved ones. You only have I known of all the nations of the earth; therefore, I will punish you for your iniquities.

He will not kill His children, nor treat them as a judge treats a criminal, for they are not under the law, but under grace; but He will chasten them and treat them as a father chastens his child – out of love. Oh! that we might have grace to walk before Him with a holy, childlike fear, so that we may walk always in the light of His countenance.
