16 Circumcise your hearts, therefore, and do not be stiff-necked any longer.

Matthew Henry's Commentary on Deuteronomy 10:16

Commentary on Deuteronomy 10:12-22

(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.

51 "You stiff-necked people! Your hearts and ears are still uncircumcised. You are just like your ancestors: You always resist the Holy Spirit!

Matthew Henry's Commentary on Acts 7:51

Commentary on Acts 7:51-53

(Read Acts 7:51-53)

Stephen was going on, it seems, to show that the temple and the temple service must come to an end, and it would be the glory of both to give way to the worship of the Father in spirit and in truth; but he perceived they would not bear it. Therefore he broke off, and by the Spirit of wisdom, courage, and power, sharply rebuked his persecutors. When plain arguments and truths provoke the opposers of the gospel, they should be shown their guilt and danger. They, like their fathers, were stubborn and wilful. There is that in our sinful hearts, which always resists the Holy Ghost, a flesh that lusts against the Spirit, and wars against his motions; but in the hearts of God's elect, when the fulness of time comes, this resistance is overcome. The gospel was offered now, not by angels, but from the Holy Ghost; yet they did not embrace it, for they were resolved not to comply with God, either in his law or in his gospel. Their guilt stung them to the heart, and they sought relief in murdering their reprover, instead of sorrow and supplication for mercy.
