Jeremiah 31:27-36

Jeremiah 31:27. Behold, the days come, saith the Lord, that I will sow the house of Israel and the house of Judah with the seed of man, and with the seed of beast. And it shall come to pass, that like as I have watched over them, to pluck up, and to break down, and to throw down, and to destroy, and to afflict; so will I watch over them, to build, and replant, saith the Lord. In those days they shall say no more, The fathers have eaten a sour grape, and the children's teeth are set on edge. But every one shall die for his own iniquity: every man that eateth the sour grape. his teeth shall be set on edge. Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah: not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord: but this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.

This is the central truth of all Scripture, it is the basis of all Scripture. When Paul desires to set forth the covenant of grace, he appeals to this passage. Twice, in the Epistle to the Hebrews, he bases an argument upon it, and after quoting it, adds, «Whereof the Holy Ghost also is a witness to us.» Brethren and sisters in Christ, under the first covenant we are ruined; there is no salvation for us but under this new covenant, wherefore let us read to our joy and comfort what the promises and provisions of that new covenant are.

Jeremiah 31:34. And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.

Pardoned sin, as well as the change of nature, is implied in the writing of the law upon the heart. Oh, what a privilege it is to be among these covenanted people! How shall we know whether we belong to them? The seal of the covenant is faith in Christ; I mean the personal seal upon the heart and conscience. Thou believest in Jesus Christ as thy Saviour, thou art trusting alone to his atoning sacrifice, then God is in covenant with thee, for Jesus is the Mediator of the new covenant, and he who hath Christ hath the Surety of the covenant, and he shall have in due time every blessing which that covenant guarantees.

Jeremiah 31:35. Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name: if those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever. Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD.

Now Israel still standeth as a people separate from all others, and there is still before the literal seed of Israel a great and glorious future; but as for the spiritual Israel, who worship God in the Spirit, and have no confidence in the flesh, God will sooner blot out the sun and moon than cast away his people, or any one of them. They shall all be his people, and he shall be their God; he will preserve them, and he will keep his covenant with them for ever and for ever, blessed be his holy name, the name of Jehovah, the God of the covenant which cannot be broken!
