Back at the on-campus church, the readings were Acts 4:32-35, 1 John 1:1-2:2, and John 20:19-31 (sermon text).
War wounds persist for years as physical and emotional scars. Even so in Christ's case - the disciples saw clearly the wounds in His hands, feet, and side. Their own wounds were still fresh; they were prisoners of their own fear until Jesus came to give them peace. Thus His scars are a gift from God, showing the risen Christ's true identity.
What do the scars show? That He was crucified for my sins, was raised for my salvation. He won the war against sin, death, and Satan for me! Therefore I have peace with God. The means: a greeting and a gift, through my partaking of His body and blood under the bread and wine.
Reexamine your own scars. Perhaps they're actually present, indicating that healing has occurred. Perhaps your wounds are deep, still fresh, still festering and gaping. But, since Christ has won for us the victory, your scars are transformed by His. Remain concerned about your open wounds - let Christ heal them. Then share Him with the other wounded.
By His wounds we are healed.
