Jesus is the Revealer and the Redeemer. He has revealed that the blood sacrifices of the old covenant are simply a picture of the redemption that God makes available because of His total and unconditional love for mankind. The writer to the Hebrews encourages those suffering to immerse themselves in Jesus, the viewable expression of the unconditional love of God, rather than seeking answers in increased religious activity. Jesus is the Redeemer who brought us back into intimacy with the Father and His family on earth. Seeing' the risen Christ changes everything.
Religious activity changes nothing.
The writer to the Hebrews draws on the Old Testament for the authority to place Jesus on the highest place. Refocus your lives away from religious activity and toward an intimate relationship with the Lord and His Family. He has everlasting authority. Give Him the opportunity to have His will done on earth through your submission. The Lord is always interceding for us.
