And the graves were opened; and many bodies of the saints who had fallen asleep were raised; and coming out of the graves after His resurrection, they went into the holy city and appeared to many. Matt 27:52-53
This scripture has always held a special interest to me. Before this verse, an earthquake occurred at the death of Jesus, which would account for the opening of the graves. Another earthquake takes place three days later at His resurrection. (cf. Matt 28:2)
At this point the dead in Christ, whose graves had previously opened, also resurrected and visited with the living in Jerusalem.
There is no indication how long these resurrected saints stayed around. Perhaps they lived out the remainder of a life until they died again, which would be the case with Lazarus, brother of Mary and Martha.
I know the next resurrection will never end in death again.
When this corruptible has put on incorruption, and this mortal has put on immortality, then shall be brought to pass the saying that is written: “Death is swallowed up in victory.” 1 Cor 15:54
And the dead in Christ will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. 1 Thess 4:16-18
