The main point is that Jesus is no ordinary, weak, sinful, dying, priest. He is strong, pure, sinless, and has an indestructible life. He is the Son of God. Jesus Christ has not just come to fit into the earthly system of the priesthood as the greatest and final human priest. Rather, he has come to fulfill and end this system. This means that the entire essence of worship which we see in the Old Testament has been radically refocused onto Jesus himself. Worship has now become a “spiritual” thing, as opposed to merely an “physical” thing. The physical is still important, but the spiritual is so significant that all of external life (not just church life) has now become an expression of our worship. Worship is now something that can and should happen all the time and everywhere.
31 Whether you eat or drink, or whatever you do, do all to the glory of God. 1 Corinthians 10:31 ESV
