Son Over His Own House

And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after; but Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.      Hebrews 3:5-6
One purpose of the book of Hebrews is to show that Jesus Christ is superior to the religious laws and regulations and the sacrificial system of the Old Testament. These verses are part of an argument by the writer of the book that Jesus is superior to Moses, the great deliverer and lawgiver of God’s people in Old Testament times.
Moses was faithful in his house, or the household of God’s people of faith. But he was nothing more than a servant in this house. But Jesus was a Son over His Own House, or the church that He founded by His sacrificial death. Because a son who rules over a household is superior to a servant in that house, this means that Jesus is superior to Moses. 
These verses refer to a time in the wilderness when Moses’ brother and sister, Aaron and Miriam, questioned his leadership over the people of Israel. God put an end to their rebellion by pointing out that Moses was His true prophet, “who is faithful in all mine house”.
But no matter how faithful Moses had been to God, Jesus was even more so. He was God’s own Son, who gave His life to set people free from their bondage to sin. All Christians are blessed by the faithfulness that Jesus demonstrated to God’s redemptive plan.
