6:1-8 Every part of the truth and will of God should be set before all who profess the gospel, and be urged on their hearts and consciences. We should not be always speaking about outward things; these have their places and use, but often take up too much attention and time, which might be better employed. The humbled sinner who pleads guilty, and cries for mercy, can have no ground from this passage to be discouraged, whatever his conscience may accuse him of. Nor does it prove that any one who is made a new creature in Christ, ever becomes a final apostate from him. The apostle is not speaking of the falling away of mere professors, never convinced or influenced by the gospel. Such have nothing to fall away from, but an empty name, or hypocritical profession. Neither is he speaking of partial declinings or backslidings. Nor are such sins meant, as Christians fall into through the strength of temptations, or the power of some worldly or fleshly lust. But the falling away here mentioned, is an open and avowed renouncing of Christ, from enmity of heart against him, his cause, and people, by men approving in their minds the deeds of his murderers, and all this after they have received the knowledge of the truth, and tasted some of its comforts. Of these it is said, that it is impossible to renew them again unto repentance. Not because the blood of Christ is not sufficient to obtain pardon for this sin; but this sin, in its very nature, is opposite to repentance and every thing that leads to it. If those who through mistaken views of this passage, as well as of their own case, fear that there is no mercy for them, would attend to the account given of the nature of this sin, that it is a total and a willing renouncing of Christ, and his cause, and joining with his enemies, it would relieve them from wrong fears. We should ourselves beware, and caution others, of every approach near to a gulf so awful as apostacy; yet in doing this we should keep close to the word of God, and be careful not to wound and terrify the weak, or discourage the fallen and penitent. Believers not only taste of the word of God, but they drink it in. And this fruitful field or garden receives the blessing. But the merely nominal Christian, continuing unfruitful under the means of grace, or producing nothing but deceit and selfishness, was near the awful state above described; and everlasting misery was the end reserved for him. Let us watch with humble caution and prayer as to ourselves.
4. We must "go on toward perfection"; for if we fall away, after having received enlightenment, it will be impossible to renew us again to repentance.
for those—"in the case of those."
once enlightened—once for all illuminated by the word of God taught in connection with "baptism" (to which, in Heb 6:2, as once for all done," once enlightened" here answers); compare Eph 5:26. This passage probably originated the application of the term "illumination" to baptism in subsequent times. Illumination, however, was not supposed to be the inseparable accompaniment of baptism: thus Chrysostom says, "Heretics have baptism, not illumination: they are baptized in body, but not enlightened in soul: as Simon Magus was baptized, but not illuminated." That "enlightened" here means knowledge of the word of truth, appears from comparing the same Greek word "illuminated," Heb 10:32, with Heb 10:26, where "knowledge of the truth" answers to it.
tasted of the heavenly gift—tasted for themselves. As "enlightened" refers to the sense of sight: so here taste follows. "The heavenly gift"; Christ given by the Father and revealed by the enlightening word preached and written: as conferring peace in the remission of sins; and as the Bestower of the gift of the Holy Spirit (Ac 8:19, 20),
made partakers of the Holy Ghost—specified as distinct from, though so inseparably connected with, "enlightened," and "tasted of the heavenly gift," Christ, as answering to "laying on of hands" after baptism, which was then generally accompanied with the impartation of the Holy Ghost in miraculous gifts.
