The resurrection of Jesus Christ separates the religions of the world from belief in Christ.
Romans 5 declares that we are saved by His (resurrection) life.
Other faiths that regard or “tip the hat” to Jesus ignore His resurrection, or refuse it. However, the death, burial and resurrection are the core tenants of the Gospel.
He who has the Son has the Father also. He who refuses the Son refuses the Father also. The Son is the one who was raised from the dead. This is key, and those who do not acknowledge His resurrection are speaking about another and not the Son. (See 1 John 2:20-25)
Death, burial and resurrection has a form in our lives this side of the grave; repentance or turning from our old life, being buried with Him in baptism, and raised to new life (in a non ultimate sense) as we come up out of the water. Of course we could go on to talk about Jesus being the first fruits of those raised from the dead… perhaps later.
New life requires the deposit of the old one, which precedes and makes way for God’s glorious grace expressed in the power to raise the dead.
This is the major divergence of “truths” and element of separation.
It would be hard to overstate the importance of Jesus’ resurrection. Missing or downplaying this central point can also be traced to a parallel of a weak walk among believers. Denominations within the Christian faith who don’t emphasize this is as essential truth can be observed as lacking powerful expression of breaking from the old and walking in new life in Christ. We, like others, descend into philosophy. The further we get away from the resurrection, the more its power recedes from our experience.
This is the Gospel in its initial and core essence and was what the apostles were sent to proclaim among the nations. Persecution erupted in the face of it. It’s one thing to say Jesus was raised from the dead and another thing to demonstrate it, which they did. Perhaps this is something we are largely missing in our times.
