Hebrews 2:3

“How shall we escape, etc..] The righteous judgment of God, and eternal punishment: if we neglect so great salvation? as the Gospel is, which is called salvation; in opposition to the law, which is the ministration of condemnation; and because it is a declaration of salvation by Christ; and is the means of bringing it near, and of the application of it in conversion, and so is the power of God unto it: and it is a “great” salvation; the Gospel which reveals it is great, for the author of it is Christ; it has been confirmed by miracles, and attended with great success; and has in it great things, great mysteries, and exceeding great and precious promises: and the salvation which it declares is…”

“we--who have received the message of salvation so clearly delivered to us (compare Heb 12:25). so great salvation--embodied in Jesus, whose very name means "salvation," including not only deliverance from foes and from death, and the grant of temporal blessings (which the law promised to the obedient), but also grace of the Spirit, forgiveness of sins, and the promise of heaven, glory, and eternal life (Heb 2:10). which--"inasmuch as it is a salvation which began," &c. spoken by the Lord--as the instrument of proclaiming it. Not as the law, spoken by the instrumentality of angels (Heb 2:2). Both law and Gospel came from God; the difference here referred to lay in the instrumentality by which…”

“How shall we escape - How shall we escape the just recompense due to transgressors? What way is there of being saved from punishment, if we suffer the great salvation to be neglected, and do not embrace its offers? The sense is, that there is no other way of salvation, and the neglect of this will be followed by certain destruction. why it will, the apostle proceeds to show, by stating that this plan of salvation was proclaimed first by the Lord himself, and had been confirmed by the most decided and amazing miracles. If we neglect - It is not merely if we commit great sins. Not, if we are murderers, adulterers, thieves, infidels, atheists, scoffers. It is, if we merely “neglect” this…”

“So great a salvation - A deliverance from so great wickedness and misery, into so great holiness and happiness. This was first spoken of (before he came it was not known) by Him who is the Lord - of angels as well as men. And was confirmed to us - Of this age, even every article of it. By them that had heard him - And had been themselves also both eye - witnesses and ministers of the word. Hebrews 2:4”

“2:3 So what makes us think we can escape? Here the author presses the full force of the danger of turning away from Christ and his salvation. There is no escape from punishment for those who walk away, and the punishment will be of the greatest severity (cp. 6:4-12; 10:26-31; 12:29; Rom 2:5; 1 Thes 2:16). • Salvation refers to God’s acts on behalf of his people. For example, God saved his people through the exodus from Egypt (Deut 26:5-9). In the New Testament, salvation primarily refers to Christ’s work of rescuing people from the penalty of sin and giving them new life by his sacrificial death on the cross (Heb 5:9-10). This salvation was first announced by the Lord Jesus himself (e.g.,…”
