Heb:3:19 So we see that they were not able to enter, because of their unbelief. A warning against unbelief. All who were rescued from Egypt, all who were able to see the delivering hand of the Almighty God, was not able to enter God's rest because of their unbelief. Unbelief results in unrest. A sinful unbelieving heart turns you away from the loving God (v:10). Sin's deceitfulness is that it will harden your heart in unbelief. We have to hold firmly to the end. Hardening of heart is equivalent to rebellion. And therefore hardening of heart, unbelief and rebellion are all synonyms that lead to unrest. Just as they perished in wilderness with lack of rest because of unbelief, you too will end up in unrest because of unbelief. Beware. Be aware.

Heb:3:3 Jesus has been found worthy of greater honour than Moses. Jesus is superior to Moses, because He was faithful to the One who appointed Him. The builder has greater honour than the house itself. God is the builder. Therefore isn't God more important than Moses. And Jesus is the Son of God. We are God's house. Moses is a faithful servant who build God's house. But Jesus is the Son of God. This is of much religious significance to the Hebrew community, that He is speaking to, for whom Moses is the pioneer. Now for us Christians, tradition, genealogy, name , fame will carry no relevance. Only Jesus who is greater than everything.
