Hebrews 12:25

See that ye refuse not him that speaketh (He alludes to his having just said that his blood speaketh;) namely, Christ, who speaks to you in the gospel, and by his Spirit and messengers, and whose speaking, even now, is a prelude to the final scene. In this command the apostle has respect to the double solemn charge given by God to his church to hear and obey his Son: the first, Deuteronomy 18:15; Deuteronomy 18:19, The Lord thy God will raise up unto thee a prophet, unto him ye shall hearken, &c. A charge intended to prepare the church for their duty in the proper season. The other charge was given immediately from heaven, Matthew 17:5; This is my beloved Son, hear ye him. This is the foundation of all gospel faith and obedience, and the formal reason of the condemnation of all unbelievers. God hath commanded all men to hear; that is, to believe and obey his Son Jesus Christ. Hence he hath given command to others to preach the gospel to all individuals. They who believe them believe in Christ; and they who believe in Christ, through him, believe in God, (1 Peter 1:21,) so that their faith is ultimately resolved into the authority of God himself. And in like manner, they who refuse them, who hear them not, do thereby refuse Christ himself; and, by so doing, reject the authority of God, who hath given this command to hear him, and hath taken on himself to require it when it is neglected. For if they escaped not divine vengeance, who refused him that spake Greek, χρηματιζοντα, literally, that gave forth oracles; (namely, Moses, who delivered the law by inspiration of God;) on earth Who received his message on earth, and delivered it only from mount Sinai, and whose oracles and doctrines were but earthly and carnal, in comparison of Christ's; much more shall we not escape Still greater vengeance; if we turn away from him that speaketh from heaven Who received his message in the bosom of the Father, came down from heaven to deliver it to us, and now addresses us not only in the solemn discourses which he uttered in the days of his flesh, sealed with his blood, and confirmed by his resurrection and ascension; but speaks to us from heaven by his Spirit in his apostles, evangelists, and other faithful ministers, and (he might have added) manifests that he does so by the mighty signs and wonders which he enables many of them to perform; and by the success he gives to the word of his grace which proceeds from their lips. See on Hebrews 2:2; Hebrews 10:28.
