4 Circumcise yourselves to the Lord, circumcise your hearts, you people of Judah and inhabitants of Jerusalem, or my wrath will flare up and burn like fire because of the evil you have done- burn with no one to quench it.
16 Circumcise your hearts, therefore, and do not be stiff-necked any longer.
(Read Deuteronomy 10:12-22)
We are here taught our duty to God in our principles and our practices. We must fear the Lord our God. We must love him, and delight in communion with him. We must walk in the ways in which he has appointed us to walk. We must serve him with all our heart and soul. What we do in his service we must do cheerfully, and with good will. We must keep his commandments. There is true honour and pleasure in obedience. We must give honour to God; and to him we must cleave, as one we love and delight in, trust in, and from whom we have great expectations. We are here taught our duty to our neighbour. God's common gifts to mankind oblige us to honour all men. And those who have themselves been in distress, and have found mercy with God, should be ready to show kindness to those who are in the like distress. We are here taught our duty to ourselves. Circumcise your hearts. Cast away all corrupt affections and inclinations, which hinder you from fearing and loving God. By nature we do not love God. This is original sin, the source whence our wickedness proceeds; and the carnal mind is enmity against God, for it is not subject to the law of God, neither indeed can be; so then they that are in the flesh cannot please God, Romans 8:5-9. Let us, without delay or reserve, come and cleave to our reconciled God in Jesus Christ, that we may love, serve, and obey him acceptably, and be daily changed into his image, from glory to glory, by the Spirit of the Lord. Consider the greatness and glory of God; and his goodness and grace; these persuade us to our duty. Blessed Spirit! Oh for thy purifying, persevering, and renewing influences, that being called out of the state of strangers, such as our fathers were, we may be found among the number of the children of God, and that our lot may be among the saints.
6 The Lord your God will circumcise your hearts and the hearts of your descendants, so that you may love him with all your heart and with all your soul, and live.
(Read Deuteronomy 30:1-10)
In this chapter is a plain intimation of the mercy God has in store for Israel in the latter days. This passage refers to the prophetic warnings of the last two chapters, which have been mainly fulfilled in the destruction of Jerusalem by the Romans, and in their dispersion to the present day; and there can be no doubt that the prophetic promise contained in these verses yet remain to come to pass. The Jewish nation shall in some future period, perhaps not very distant, be converted to the faith of Christ; and, many think, again settled in the land of Canaan. The language here used is in a great measure absolute promises; not merely a conditional engagement, but declaring an event assuredly to take place. For the Lord himself here engages to "circumcise their hearts;" and when regenerating grace has removed corrupt nature, and Divine love has supplanted the love of sin, they certainly will reflect, repent, return to God, and obey him; and he will rejoice in doing them good. The change that will be wrought upon them will not be only outward, or consisting in mere opinions; it will reach to their souls. It will produce in them an utter hatred of all sin, and a fervent love to God, as their reconciled God in Christ Jesus; they will love him with all their hearts, and with all their soul. They are very far from this state of mind at present, but so were the murderers of the Lord Jesus, on the day of Pentecost; who yet in one hour were converted unto God. So shall it be in the day of God's power; a nation shall be born in a day; the Lord will hasten it in his time. As a conditional promise this passage belongs to all persons and all people, not to Israel only; it assures us that the greatest sinners, if they repent and are converted, shall have their sins pardoned, and be restored to God's favour.
28 A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical.
(Read Romans 2:25-29)
No forms, ordinances, or notions can profit, without regenerating grace, which will always lead to seeking an interest in the righteousness of God by faith. For he is no more a Christian now, than he was really a Jew of old, who is only one outwardly: neither is that baptism, which is outward in the flesh: but he is the real Christian, who is inwardly a true believer, with an obedient faith. And the true baptism is that of the heart, by the washing of regeneration and the renewal of the Holy Ghost; bringing a spiritual frame of mind, and a willing following of truth in its holy ways. Let us pray that we may be made real Christians, not outwardly, but inwardly; in the heart and spirit, not in the letter; baptized, not with water only, but with the Holy Ghost; and let our praise be, not of men, but of God.
11 In him you were also circumcised with a circumcision not performed by human hands. Your whole self ruled by the flesh was put off when you were circumcised by Christ,
(Read Colossians 2:8-17)
There is a philosophy which rightly exercises our reasonable faculties; a study of the works of God, which leads us to the knowledge of God, and confirms our faith in him. But there is a philosophy which is vain and deceitful; and while it pleases men's fancies, hinders their faith: such are curious speculations about things above us, or no concern to us. Those who walk in the way of the world, are turned from following Christ. We have in Him the substance of all the shadows of the ceremonial law. All the defects of it are made up in the gospel of Christ, by his complete sacrifice for sin, and by the revelation of the will of God. To be complete, is to be furnished with all things necessary for salvation. By this one word "complete," is shown that we have in Christ whatever is required. "In him," not when we look to Christ, as though he were distant from us, but we are in him, when, by the power of the Spirit, we have faith wrought in our hearts by the Spirit, and we are united to our Head. The circumcision of the heart, the crucifixion of the flesh, the death and burial to sin and to the world, and the resurrection to newness of life, set forth in baptism, and by faith wrought in our hearts, prove that our sins are forgiven, and that we are fully delivered from the curse of the law. Through Christ, we, who were dead in sins, are quickened. Christ's death was the death of our sins; Christ's resurrection is the quickening of our souls. The law of ordinances, which was a yoke to the Jews, and a partition-wall to the Gentiles, the Lord Jesus took out of the way. When the substance was come, the shadows fled. Since every mortal man is, through the hand-writing of the law, guilty of death, how very dreadful is the condition of the ungodly and unholy, who trample under foot that blood of the Son of God, whereby alone this deadly hand-writing can be blotted out! Let not any be troubled about bigoted judgments which related to meats, or the Jewish solemnities. The setting apart a portion of our time for the worship and service of God, is a moral and unchangeable duty, but had no necessary dependence upon the seventh day of the week, the sabbath of the Jews. The first day of the week, or the Lord's day, is the time kept holy by Christians, in remembrance of Christ's resurrection. All the Jewish rites were shadows of gospel blessings.

Commentary on Jeremiah 4:3-4
(Read Jeremiah 4:3-4)
An unhumbled heart is like ground untilled. It is ground which may be improved; it is our ground let out to us; but it is fallow; it is over-grown with thorns and weeds, the natural product of the corrupt heart. Let us entreat the Lord to create in us a clean heart, and to renew a right spirit within us; for except a man be born again, he cannot enter into the kingdom of heaven.
