Matthew 7:21

Not everyone that saith unto me Lord, Lord
Not every one that calls Christ his Lord and Master, professes subjection to him, or that calls upon his name, or is called by his name; or makes use of it in his public ministrations. There are many who desire to be called, and accounted Christians, and who make mention of the name of Christ in their sermons, only to take away their reproach, to cover themselves, and gain credit with, and get into the affections and goodwill of the people; but have no hearty love to Christ, nor true faith in him: nor is it their concern to preach his Gospel, advance his glory, and promote his kingdom and interest; their chief view is to please men, aggrandize themselves, and set up the power of human nature in opposition to the grace of God, and the righteousness of Christ. Now not everyone of these, no, not any of them,

shall enter into the kingdom of heaven.
This is to be understood not of the outward dispensation of the Gospel, or the Gospel church state, or the visible church of Christ on earth, in which sense this phrase is sometimes used; because such persons may, and often do, enter here; but of eternal glory, into which none shall enter,

but he that doeth the will of my Father which is in heaven.
This, as it may regard private Christians, intends not merely outward obedience to the will of God, declared in his law, nor barely subjection to the ordinances of the Gospel; but more especially faith in Christ for life and salvation; which is the source of all true evangelical obedience, and without which nothing is acceptable to God. He that seeth the Son, looks unto him, ventures on him, commits himself to him, trusts in him, relies on him, and believes on him for righteousness, salvation, and eternal life, he it is that does the will of the Father, and he only; and such an one, as he is desirous of doing the will of God in all acts of cheerful obedience to it, without dependence thereon; so he shall certainly enter the kingdom of heaven, and have everlasting life; see ( John 6:40 ) but as these words chiefly respect preachers, the sense of them is this, that only such who are faithful dispensers of the word shall enter into the joy of their Lord. Such do the will of Christ's Father, and so his own, which are the same, who fully and faithfully preach the Gospel of the grace of God; who declare the whole counsel of God, and keep back nothing that is profitable to the souls of men; who are neither ashamed of the testimony of Christ, nor afraid of the faces of men; but as they are put in trust with the Gospel, so they speak it boldly, with all sincerity, not as pleasing men, but God, and commend themselves to every man's conscience in the sight of God: such as these shall have an abundant entrance into the kingdom and glory of God. The Vulgate Latin adds this clause, "he shall enter into the kingdom of heaven", and so does Munster's Hebrew edition of the Gospel according to Matthew.
