Luk 20:34-36

(34) And Jesus answering said unto them, The children of this world marry, and are given in marriage:

(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:

(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.

Rev 14:4

(4) These are they which were not defiled with women (marriage); for they are virgins (Unmarried). These are they which follow the Lamb whithersoever he goeth. These were redeemed from among men, being the firstfruits unto God and to the Lamb.
