Whether it is called Easter or Resurrection Sunday is not as important as the event and purpose of the resurrection. However, the timing of the crucifixion and resurrection is significantly meaningful. The resurrection of Jesus is the culmination of all things meaningful, faith and fact, in establishing a relationship with God.
God used the timing, which occurred just after “Passover” and during the Feast of Unleavened Bread, to illustrate the ultimate sacrifice He made for sinners. Without this sacrifice, Christianity would be an empty religion. Every purpose of Jesus Christ, His atonement for sin, would be unfulfilled and the foundation of Christianity would fall apart.
The Passover commemorates God’s “passing over” the Hebrew’s homes by the angel of death (Exodus 12:29). By accepting Jesus, we are promised eternal life and we are saved from spiritual death. The Feast of Unleavened Bread (verse 15) begins with unleavened bread (made without yeast) and sacrificing an unblemished, sacrificial lamb. Leavening represents the escape from bondage and sin. Jesus is called the Lamb of God through whom the only escape is possible.
Jesus’ crucifixion and resurrection are God’s provision for the perfect and final sacrifice for man’s sins. God requires no other payment for sins! With this provision, mankind is granted opportunity for new life by the forgiveness of sin and escape from its bondage. It is ours for the mere acceptance of this gift.
This is the key event in the New Testament where it is proclaimed throughout. All four Gospels report the miraculous event. In Matthew 28:6 the angel declared “He is not here: for he is risen!” Mark 16:6 reports “‘Don’t be alarmed,’ [the angel] said. ‘You are looking for Jesus the Nazarene, who was crucified. He has risen! He is not here. See the place where they laid him.’”
In Luke 24:46-48, the risen Jesus gave His disciples a greater understanding of the resurrection when He told them: “This is what is written: The Christ will suffer and rise from the dead on the third day, and repentance and forgiveness of sins will be preached in his name to all nations, beginning at Jerusalem. You are witnesses of these things.” Jesus foretells of His resurrection in John 16, then to one of the doubting witnesses, Thomas, He says the following in John 20:29: “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”
While Jesus was admired and praised as a teacher, healer, and for performing miracles, He was put to death on the cross. But God raised Him from the dead. Had the witnesses not believed what they saw, Christianity would not have spread across the globe and remained a profound belief to this day.
