Contemporary English Version (CEV)
Hebrews is more of a sermon than a letter, and the point of the this section is to paint a difference between Jesus Christ and the angels. Perhaps the argument was going around that Jesus was just another angel, no different than the rest, but the preacher here is emphasizing that Jesus is different. Jesus is the Son of God, and he will rule forever. The angels were created, but Jesus will sit on a throne eternally.
Think about that for a second -- picture the majesty of Christ, sitting at the right hand of God, in the throne room adorned with the power and majesty that rightly belongs to God the Father. This is the true identity of Jesus.
And Christ sets all of that down, comes to earth and ascends the cross, dying like a common criminal because he loves you and wants to remove your punishment from sin, so that you may have life, and have it eternally and abundantly, worshiping God forever. That's how much Christ loves you.
