The Lord Jesus Christ had power to raise the dead during His earthly ministry, but he taught there is a day that is yet to come when all the dead will be raised to appear before the Judgement Seat of Christ.
John.5.28-29Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
