And I will put my Spirit within you - To keep the heart of flesh alive, the feeling heart still sensible, the loving heart still happy. I will put my Spirit, the great principle of light, life, and love, within you, to actuate the new spirit, and to influence the new affections and passions; that the animal spirit may not become brutish, that the mental powers become not foolish. I will put my Spirit within you, so that as the new spirit may influence the new heart, so will My Spirit influence Your new spirit, that each may have a proper mover; and then all will be pure, regular, and harmonious, when passion is influenced by reason, and reason by the Holy Ghost.

And the cause shall be evidenced by the effects; for I will cause you to walk in my statutes - not only to believe and reverence my appointments relative to what I command you to perform; but ye shall walk in them, your conduct shall be regulated by them. "And ye shall keep my judgments;" whatsoever I enjoin you to avoid. And ye shall do them - ye shall not only avoid every appearance of evil, but keep all my ordinances and commandments unblamably.

Here is the salvation that God promises to give to restored Israel; and here is the salvation that is the birthright of every Christian believer: the complete destruction of all sin in the soul, and the complete renewal of the heart; no sin having any place within, and no unrighteousness having any place without.

"But where are they that are thus saved?"

Ans. Wherever true Christians are to be found.

"But I know many true Christians that have not this salvation, but daily mourn over their evil hearts?"

Ans. They may be sincere, but they are not true Christians; i.e., such as are saved from their sins; the true Christians are those who are filled with the nature and Spirit of Christ. But I will ask a question in my turn:

"Do those you mention think it a virtue to be always mourning over their impurities?" Most certainly. Then it is a pity they were not better instructed. It is right they should mourn while they feel an impure heart; but why do they not apply to that blood which cleanses from all unrighteousness, and to that Spirit which cleanses the very thoughts of the heart by his inspiration? Many employ that time in brooding and mourning over their impure hearts, which should be spent in prayer and faith before God, that their impurities might be washed away. In what a state of nonage are many members of the Christian Church!

And I will put my Spirit within you,.... My Holy Spirit, as the Targum; the Spirit of holiness; the author of internal sanctification, of the new heart and spirit, and of the fleshy one before mentioned; and through whose grace and strength the saints do what is after said they shall do:

and cause you to walk in my statutes: men are first made alive by the Spirit of God, and have spiritual strength put into them, who of themselves can do nothing; by means of which they are enabled to walk in all the commandments and ordinances of the Lord, and to continue in the observation of them; which walking in them supposes:

and ye shall keep my judgments, and do them; being constrained by the love of God; influenced by the grace of Christ; and strengthened by the blessed Spirit: and such persons observe and do them willingly and cheerfully; from a principle of love; in faith, and to the glory of God; without any mercenary and selfish views; without trusting to, and depending upon, what is done for salvation.

And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.

36:27 My spirit - The holy spirit of God, which is given to, and dwelleth in all true believers. And cause you - Sweetly, powerfully, yet without compulsion; for our spirits, framed by God's spirit to a disposition suitable to his holiness, readily concurs. Ye shall keep - Be willing; and able to keep the judgments, and to walk in the statutes of God, which is, to live in all holiness.

27. my spirit-(Eze 11:19; Jer 32:39). The partial reformation at the return from Babylon (Ezr 10:6, &c.; Ne 8:1-9:38) was an earnest of the full renewal hereafter under Messiah.

36:25-38 Water is an emblem of the cleansing our polluted souls from sin. But no water can do more than take away the filth of the flesh. Water seems in general the sacramental sign of the sanctifying influences of the Holy Ghost; yet this is always connected with the atoning blood of Christ. When the latter is applied by faith to the conscience, to cleanse it from evil works, the former is always applied to the powers of the soul, to purify it from the pollution of sin. All that have an interest in the new covenant, have a new heart and a new spirit, in order to their walking in newness of life. God would give a heart of flesh, a soft and tender heart, complying with his holy will. Renewing grace works as great a change in the soul, as the turning a dead stone into living flesh. God will put his Spirit within, as a Teacher, Guide, and Sanctifier. The promise of God's grace to fit us for our duty, should quicken our constant care and endeavour to do our duty. These are promises to be pleaded by, and will be fulfilled to, all true believers in every age.
