And Jesus answered and said to them, “The sons of this age marry and are given in marriage.  But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage;  nor can they die anymore, for they are equal to the angels and are sons of God, being sons of the resurrection.  But even Moses showed in the burning bush passage that the dead are raised, when he called the Lord ‘the God of Abraham, the God of Isaac, and the God of Jacob.’  For He is not the God of the dead but of the living, for all live to Him.”   

Luke 20:34-38   (NKJV)
