Jeremiah 32:39
And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them:
And I will give them one heart and one way,.... "One" and the same heart; the same heart to one as to another; gracious souls, truly converted persons, be they Jews or Gentiles, have the same experience; they have all, more or less, a sight and sense of sin, and the evil of it; are brought off of their own righteousness; are led to Christ alone for life and salvation; are made partakers of precious promises; and all have their temptations, afflictions, and trials, and can sympathize with one another: and they have the same things put into their hearts; the laws of God are written there; the doctrines of the Gospel have a place there; Christ is formed in them; the graces of the Spirit are implanted, faith, hope, love, fear, humility, and other graces. Their heart, given them at conversion, is a sincere and upright heart, not a double one; they become Israelites indeed; their faith is unfeigned; their hope is devoid of hypocrisy; their love is without dissimulation; their repentance is genuine; and they serve God uprightly with true hearts. It is also single and alone for God; he has the whole of it; their understandings are enlightened with the knowledge of him; their affections and desires are towards him: their wills are subject to him; their eye is single to his glory; their hearts are not divided between him and another object of worship; and they are also one towards another, as the first Christians were of one heart and of one soul, Acts 4:32; and such a heart is a new heart, and the gift of God: "one way" is also promised: one way of salvation, which is Christ; the one and only way of access to God; of acceptance with him; of justification before him; and of forgiveness of sin; the only true way into a Gospel church state, and to eternal glory and happiness; and which is the more excellent way; the good old way; the new and living one: one way of worship may also be intended; one Lord is to be obeyed and worshipped; one doctrine and scheme of faith to be received; one baptism to be administered, in one and the same way, to one and the same subjects, and in one and the same name; one true spiritual manner of worship, all shall come into in the latter day; and there will be no more parties among those that are called Christians; the Jews, when converted, will have no divisions nor different denominations among them; see Ephesians 4:4
that they may fear me for ever; both internally and externally; the one heart will be given them to fear and reverence him inwardly; and the one way of worship to fear or serve him outwardly, and in which they shall always continue; there will be no apostasy from the true grace of God, and no defection from his worship to superstition and idolatry:
for the good of them, and of their children after them; unity of heart; sincerity and uprightness of soul; a walking in the way of the Lord; having his fear before their eyes, and on their hearts, will issue in their spiritual good here, and in their eternal happiness hereafter; and even their posterity will reap some advantage by their good instructions and example.
