The death of Jesus Christ was not a failure. It was not a victory for Satan, either. It was not a disgrace to God or something to deny. It was something Jesus knew about and planned for because his resurrection that was the purpose of his death. If Jesus died and remained in the grave, then he would be no different from any other prophet who has died. However, Jesus did not remain dead. He came back to life.
To deny the death of Jesus Christ is to deny the will of God. Jesus submitted to the will of God. He lived the plan of God, which was to bring victory over Satan and freedom from sin through Jesus’ death and resurrection. This may be hard to accept or to understand, but if we deny it then we are hardening our hearts to the truth. When Jesus spoke of his death to his disciples, one of them, Peter, decided that it would not be right for Jesus to die. Listen to what Jesus said to him about the death of the Messiah:
From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests and teachers of the law, and that he must be killed and on the third day be raised to life. Peter took him aside and began to rebuke him. “Never, Lord!” he said. “This shall never happen to you!” Jesus turned and said to Peter, “Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men.” Matthew 16.21-23
To deny the death of Jesus Christ and his resurrection is to reject God’s plan. It is thinking like man and not like God.
