The Supreme High Priest

Hebrews 4:14-16

The word "therefore" threw me for a loop. I was looking back at the previous flow of thought from the rest of chapter four and I just couldn't figure out how the author could, in my understanding, jump from a discussion on obeying God's Word in order to enter God's Sabbath rest to Jesus being the great high priest. Turns out I wasn't looking back far enough to catch the author's train of thought. Thankfully Pastor Steve pointed me in the right direction: I had to back to the end of chapter two and the beginning of chapter three: Jesus, in becoming like us, became our merciful and faithful high priest who is able to enter into our temptations and suffering(2:17-18) therefore, let us hold firmly to the faith we profess (4:14).
There are multiple interwoven arguments and themes because holding on to the faith we profess is the theme of the previous section but the motivation for holding on to faith is the rest we can achieve when we do. Now the author turns back to his previous motivation: that Jesus empathizes with our weakness and enters into our suffering but did it without falling into sin. This gives us confidence to approach the throne of God, knowing that he hears our prayers and empathizes with our needs.
Again the author's main point is the supremacy of Christ. Jesus is the supreme high priest because he allows us direct access to the throne of God. There is no longer a veil. Also, he empathizes with and enters into our pain.
