What does Hebrews 3:4 mean?

This verse supports the general idea of Hebrews 3:3. Namely, that Jesus is superior to Moses in the same sense that a builder is superior to the house he constructs. In addition, this verse gives a crystal-clear indication that Jesus Christ is, in fact, God. Hebrews 1:2 makes a similar reference, calling Jesus the One through whom God created the world.

The author of Hebrews is explaining how the person and mission of Jesus are both far superior to those of Moses. This is not to diminish Moses at all. Rather, the point is that those who see Moses as a worthy example ought to feel even more inclined to follow Jesus. In the context of this letter, written to persecuted Jewish Christians, this is especially important. Those who cave in to persecution and return to Judaism instead of holding to their faith will suffer a loss of inheritance, as described later.
