Luk 20:34 And Jesus answering said unto them, The children of this world marry, and are given in marriage:
Luk 20:35 But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage:
Luk 20:36 Neither can they die any more: for they are equal unto the angels; and are the children of God, being the children of the resurrection.
Mar 12:24 And Jesus answering said unto them, Do ye not therefore err, because ye know not the scriptures, neither the power of God?
Mar 12:25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven.
Those who are married likely are still married after death but the scriptures say after the dead resurrect, that there is no marriage and they will be like the angels...who also do not marry.
