I've been thinking about resting on Jesus while meditating on Hebrews. I am not sure if it was the apostle who wrote this book because I have memorized many of the writings of the apostles. The author of this book is using the Old Testament, probably because the audience is Jewish, but there is a train of thought and then there will be a verse that doesn't seem to fit the flow of the passage. One is that he is very repetitive in his arguments, and they overwrite the verses of the Old Testament in his arguments. One of the verses that does not seem to follow your train of thought is the encouragement to step into your rest and then use the verse in which God did not allow those to whom the gospel was preached under Joshua to step into that rest. He speaks to people who are used to showing a lot, I mean ceremonial things. But your answer is to focus on Jesus. 

Therefore, it is repeated that he does what he says: to walk this path is to follow a follower of Christ. Or someone who is habitually focused on Christ, Christ is the rest.
Another verse that seems out of place is the verse about the word of God as a double edged sword, the rest is that Christ is speaking his word right now when he decided to keep this generation from stepping into his rest. negative to encourage them to abide in Christ?I believe he draws a huge gap between those who step into his rest and those who don't, and that makes him more determined. So they would see the covenant God made in the Old Testament; they would be reminded that God did not call the nations; In this way, they would strengthen God's sovereignty over their own self-sustaining abilities. The practical Christian life consists in deviating from indicative orientation and submission to God's Word in order to avoid the encouragement to find rest only in His Word.
