Matthew 27:51-53 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; And the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
Please note this minor point; it was many, not all who were risen. They appeared unto many but not all.
Now put yourself into that time and place as one who hears about dead relatives of others having risen and been seen, but not yours and not with your own eyes.
What is your reaction? What are you hearing? What questions do you have for these witnesses?
If you can place yourself into that moment and realize the enormity of the moment and feel the doubt as to the validity of what you are hearing, good.
Now take that new understanding and carry it with you as you witness to a lost and dying world so that you might better understand them.
We who believe are the risen. You are going to reach many, but not all. We get to be a witness of once being dead, but now live. How believable are you to those who have not yet seen? Maybe understanding their doubts, fears and perhaps even anger, might help you reach them, touch them, comfort them, and draw them nearer to our risen Christ.
I do not know what the risen from Matthew 27 had to say. I can only imagine. I only know what I have seen and what happened to me.
I know what it felt like to be dead. I know what it feels like to be risen.
Romans 6:4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
