If the bible is used in conjunction with with book of mormon for clarification, why does the bible state in Matthew 22:30 and in Mark 12:25 that 25Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother: 26Likewise the second also, and the third, unto the seventh. 27And last of all the woman died also. 28Therefore in the resurrection whose wife shall she be of the seven? for they all had her. 29Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. 30For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. 31But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, 32I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. 33And when the multitude heard this, they were astonished at his doctrine. The bible states we will not remain married in heaven, therefore there will be no physical sex in heaven. Sex would be a distraction from praising God, and that is what we are to do in heaven.
