1Therefore, holy brothers, who share in the heavenly calling, fix your thoughts on Jesus, the apostle and high priest whom we confess. 2He was faithful to the one who appointed him, just as Moses was faithful in all God's house. 3Jesus has been found worthy of greater honor than Moses, just as the builder of a house has greater honor than the house itself. 4For every house is built by someone, but God is the builder of everything. 5Moses was faithful as a servant in all God's house, testifying to what would be said in the future. 6But Christ is faithful as a son over God's house. And we are his house, if we hold on to our courage and the hope of which we boast.
Moses was a faithful servant in God's house but Jesus is a faithful son over God's house. Jesus is worthy of greater honour than Moses (or anyone/anything else) in the same way that the builder of a house has greater honour than the house itself - it's a totally different category. Jesus is not just the best thing in the house. He is in a totally different category. He built the house! He's not just the best thing part of our lives - He is our life. He's doesn't just love us - He is love, He defines what love actually means. He isn't just a teacher telling us how to get ourselves right with God - He is the way we get right with God.
Therefore, we are told to fix our thoughts on Jesus (NIV), consider Him (ESV), take a long, hard look at Him (Message). We are his house (v6) - He built the thing, He owns it, He rules over it
