16 And who was it who rebelled against God, even though they heard his voice? Wasn't it the people Moses led out of Egypt? 17 And who made God angry for forty years? Wasn't it the people who sinned, whose corpses lay in the wilderness? 18 And to whom was God speaking when he took an oath that they would never enter his rest? Wasn't it the people who disobeyed him? 19 So we see that because of their unbelief they were not able to enter his rest.
Matthew Henry's Commentary on Hebrews 3:16-19
Commentary on Hebrews 3:14-19
(Read Hebrews 3:14-19)
The saints' privilege is, they are made partakers of Christ, that is, of the Spirit, the nature, graces, righteousness, and life of Christ; they are interested in all Christ is, in all he has done, or will do. The same spirit with which Christians set out in the ways of God, they should maintain unto the end. Perseverance in faith is the best evidence of the sincerity of our faith. Hearing the word often is a means of salvation, yet, if not hearkened to, it will expose more to the Divine wrath. The happiness of being partakers of Christ and his complete salvation, and the fear of God's wrath and eternal misery, should stir us up to persevere in the life of obedient faith. Let us beware of trusting to outward privileges or professions, and pray to be numbered with the true believers who enter heaven, when all others fail because of unbelief. As our obedience follows according to the power of our faith, so our sins and want of care are according to the prevailing of unbelief in us.
