The old covenant regulations and traditions were a shadow of what was to come- Christ, the substance of the new covenant.
Since the original audience was so familiar with the old covenant this explanation of the new covenant made perfect sense.
Jesus provided the required one time blood sacrifice and is now our mediator before God.
Humanity’s contribution to salvation is providing the sin which needs atoning for. There is no shortage.
Always accurately champion Jesus as the complete sacrifice and mediator.
Jesus’ work & death on earth was purposeful in every way. Him being our mediator now is no less purposeful.
Jesus, I am eternally grateful for the work and love only you can provide.
