I believe that love is spiritual, but sex is not love, so sex is not spiritual. I believe that sex for the purpose of procreation is spiritual, since it is sex out of love for a potential new being that will be created, but aside from procreation, sex is a physical act that is engaged in to gratify the desires of the flesh in order to experience physical pleasure.
On the Spiritual Singles dating site there is a Profile question about sex, and men can choose between Not Important, Somewhat Important, Important, or Extremely Important. The bulk of men I have viewed say sex is Extremely Important. Why does a man who claims to be spiritual say that sex is ‘Extremely Important’ in a relationship? Often the same man also says that spirituality is ‘Extremely Important.’ I consider this contradictory since the man is saying two things that cannot both be true, since they are in conflict with each other.
Why pretend that sex is spiritual? Anyone who has ever read the Bible knows that sex that is engaged in to gratify the desires of the flesh is not spiritual because the flesh desires what is contrary to the Spirit.
John 3:5-7 Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. Flesh gives birth to flesh, but the Spirit gives birth to spirit. You should not be surprised at my saying, ‘You must be born again.’
John 6:63 The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit and life.
John 6:63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.
1 John 2:16 For everything in the world—the lust of the flesh, the lust of the eyes, and the pride of life—comes not from the Father but from the world.
Galatians 5:16-17 So I say, walk by the Spirit, and you will not gratify the desires of the flesh. For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want.
