The mystery of Jesus Christ has existed during and since the time of His three and a half years ministry on earth. Jesus told His disciples in Mat. 13:11 it was given to them to know the mysteries of the kingdom of heaven. Paul also said in Col. 1:26 this mystery has been revealed to the saints. A part of the mystery that has been revealed is that Jesus Christ is our Passover and what this means to the saints and eventually to the world.
