The resurrection of Jesus is critical to the Christian message. Without the resurrection the Christian faith does not exist. Everything is wrapped up in the resurrection. If Jesus did not rise from the dead then the faith of Christians is in vain.
Some might think that the most important message of the Christians is that Jesus was born of a virgin. Others might think that it is the message of peace. Some more might think it is to love your neighbor as yourself. Then there are those who will proclaim to their own death that the most important message is the crucifixion of Jesus and he paid the price of sin for those who are to be saved. Yet it is without doubt the most important message for the world is Jesus rose from the dead.
Why is the resurrection the most important teaching of the Christians?
The resurrection of Jesus provides us with hope. If there is no resurrection of the dead then there is no hope of this life having any purpose and there is no hope of eternal life.
While the birth of Jesus is a miracle in itself, this is meaningless unless Jesus is resurrected from the dead. The fact that Jesus preached peace and preached love and performed miracles becomes meaningless if Jesus was not resurrected from the dead. The fact that Jesus was crucified and paid the price for sin on behalf of all mankind is meaningless if he was not raised from the dead.
Mohammed wrote in the Koran that Jesus was born of a Virgin, but refused to accept that Jesus rose from the dead. It is one thing to acknowledge that God can do a miracle and cause a virgin to have a child, but it is another to acknowledge that Jesus rose from the dead.
To acknowledge that Jesus rose from the dead is to acknowledge that He is alive today. More than this, to acknowledge Jesus rose from the dead is to imply that he is God in human form. Both these issues could be problematic to anyone who was attempting to start a political movement under the guise of religion.
Because Jesus rose from the dead, He is able to be known by you and me. Many people have discovered Jesus and entered into a personal relationship with Him. This is more than just believing a message. A personal relationship means something special that occurs with you and another person. God is able to do this through the Holy Spirit which is given to everyone who enters into this relationship.
This is the difference between being somebody who truly belongs to Christ and people who call themselves Christian yet do not know Jesus Christ as their Lord and Savior.
As the Bible states: If you believe Jesus has been raised from the dead, then you have the right to be heard by God.
