The author of the epistle to the Hebrews admonishes his readers to imitate the faith of their leaders, those who spoke to them the word of God (Hebr 13:7). This is the kind of faith which is awoken when a person goes through what many call the dark nights of the soul. Paul elaborates on this in his first chapter in his second letter to the Corinthians when he observes that the perils he and his friends went through was to make them not rely on themselves, but on God who raises the dead. When the illusion about independent self is burned off what remains in a mature faith in God who can do all things in and through us.
On the day the Lord made the covenant with Abraham, our father of faith, a deep sleep fell on Abraham. Dreadful and great darkness fell upon him. Before Abraham could enter a perfect rest from all his works he first had to go through his own dark nights of the soul experience there in the desert. While Abraham was fast asleep resting from his works God made the covenant with Jesus Christ, who represented Abraham and his seed. In making the covenant with God Abraham learned not to rely on himself, but on God who is mighty to accomplish everything He has promised Abraham and his descendants of faith. In the midst of our travails God reminds us about His promises and encourages and comforts us, like He did to Abraham. We are not responsible or accountable to observe the covenant terms. The covenant was cut between God and Jesus, and Jesus has met all the requisites.
