One of the greatest attributes of Christ is that Jesus makes his disciples “holy” and treats us like brothers & sisters, v1. (brothers & sisters) 2nd Corinthians 6:18. He is the only one who can make us holy. Moses needed people’s obedience to the law in applying animal’s blood, before anyone or anything was considered holy in obedience to the old law. Moses was highly revered among the Jews for obvious reasons. So the delicate comparison does not quote Moses’ faults; but rather, he acknowledges that “Moses was faithful in all His house” (Heb 3:2). Like Moses, it is affirmed that Jesus was sent with heavenly authority; for example, “the Apostle … of our confession” (3:1). Jesus also fulfills Aaron’s role: He is the “High Priest of our confession.” (4:14) We should “consider” Jesus in these roles, to think very carefully about their implications. It was in the context of God talking to Aaron & Miriam that He proclaimed Moses faithful to relate the law, Numbers 12:7.
Jesus Has More Glory Than Moses (Heb 3:3-6) While Moses was a faithful servant, he was a servant nonetheless. Moses inherited a nation to lead, Jesus built His nation/house: He is “a Son over His own house” (Heb 3:6) “I will build My church …” – Mt 16:18). Moses was faithful over an unfaithful people, his readers must not become like unfaithful Israel. Christians remain the house of God only “if we hold fast the confidence and the rejoicing of the hope firm to the end” (3:6). This warning clearly makes salvation conditional upon each believer maintaining his/her own faith.
Since Jesus built His house, and “He who built all things is God,” then Jesus is in a very real sense, God. What should the builder of the house receive? The greatest praise & glory!
Heb 3:7-11 is a passage which is very similar to 1st Corinthians 10:1-11 where Paul reminisces about the glorious exodus of Israel from Egypt under Moses illustrious leadership. In spite of such a grand beginning, “with most of them God was not well pleased, for their bodies were scattered in the wilderness” (1 Cor 10:5). The recipients of Hebrews are in danger of the same awful ending. Never forget who was responsible for the words in Ps 95:7-11.
A most grave warning is introduced with the word “beware” followed by two “lests”, because of the hardening of their hearts, (Heb 3:12-15). A very good antidote to apostasy is “exhort one another daily” (3:13a). It doesn’t take a high I.Q. to encourage someone, it just takes time, 1st Thessalonians 5:11 & 2nd Thessalonians 2:16-17. We should do it and pray that God helps us and works through our efforts of encouragement. The author picks up on the word “today” from the quotation of Psalms in 3:7 and makes fresh application: “… while it is called ‘Today’ …”. That is, the words of the Holy Spirit in reference to Israel’s unbelief are always applicable to us today. The coming of grace through Jesus Christ has not made apostasy impossible; God’s grace does not safeguard the believer against willful rebellion. These words are absolutely pointless if a true believer cannot depart from God. The author says one can defect and become unfaithful. Many today say such is impossible. Which shall we believe?
It is important to differentiate between sin and apostasy. The NT affirms that all men and women of faith will occasionally sin through weakness, but apostasy is the settled choice to abandon God altogether. It is this ultimate departure that is not only possible but likely if these Christians continue on their present course. It is obvious how our disobedience, if left unchecked and neglected, can subtly become unbelief to the point of being lost, when once we had been saved, Heb. 3:16-19. This letter was written to Christians, not the children of Christians. We must take personal responsibility for learning and living this message.
