For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering. For he who sanctifies and those who are sanctified all have one source. That is why he is not ashamed to call them brothers,
For because he himself has suffered when tempted, he is able to help those who are being tempted.
It was “fitting” for Jesus to be made flesh, live like us, and to be made “perfect through suffering.” This makes Him our brother. More than that, it says Jesus is not ashamed to call us brothers. He being the Son of God and we being the children of God all have one Father (“source”).
When you are tempted, and when you are suffering, you have a brother who understands. I know that I have a physical brother, Mark, who is also a brother in Christ. When I am struggling or down, I know he will listen, understand, pray for me and give me wise counsel. That is such a comfort. But even more than that, Jesus is my brother. He understands, and He listens, and He brings comfort. Jesus went through all that we have gone through, and He knows our situation completely. When we come to the throne we find mercy and grace because He is our brother.
I often think of Jesus as Lord, God, Savior, and Christ, but not as much as my brother and my friend. Maybe you think the same way, I don’t know, but take time to meditate upon Jesus being your brother and what that means for you.
