I'm glad to read in the messages above that asking God for guidance is mentioned.However waiting for God to repeat instructions that are already in the Bible can take an endless amount of time and in fact may never occur because we are expected to read the instructions for ourselves.
The Apostle Paul repeatedly taught that Christians should never get married unless they could not control themselves sexually.His teaching was different from Jesus' teaching only in that he did not threaten people if his instructions were not followed.
Luke 20:34-36 (King James Version)
34And Jesus answering said unto them, The children of this world marry, and are given in marriage:
35But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage:
36Neither can they die any more: for they are equal unto the angels; and are the children of God, being the children of the resurrection.
