This Man Is The Son of God

Jesus, when He had cried again with a loud voice, yielded up the ghost.  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.
Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, “Truly this was the Son of God.”
Matthew 27:50-54

And now I exhort you to be of good cheer: for there shall be no loss of life among you, but of the ship. For there stood by me this night the angel of God, whose I am, and whom I serve, saying, “Fear not, Paul; thou must be brought before Caesar: and, lo, God hath given thee all them that sail with thee.” Wherefore, sirs, be of good cheer: for I believe God, that it shall be even as it was told me.
Acts 27:22-25

…That I may know Him…

But what things were gain to me, those I counted loss for Christ.  Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ, and be found in Him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith: that I may know Him, and the power of His resurrection, and the fellowship of His sufferings, being made conformable unto His death; if by any means I might attain unto the resurrection of the dead.
Philippians 3:7-11

They Came Out of Their Graves, After His Resurrection

Jesus, when He had cried again with a loud voice, yielded up the ghost.  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.
Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, “Truly this was the Son of God.”  Matthew 27:50-54

These are the “First fruits” of His resurrection. So shall the rest of those be who die in the Lord Jesus Christ.
