I have read some of the other posts regarding loneliness and lust. I have dealt with both. What I have seen and felt in my lifetime I view within the context of faith. I had a very conservative faith as a teenager growing up in a Church of Christ. I heard plenty of sermons on adultery, fornication, and everything else. "The wages of sin is death" was a phrase that was "hammered" into my head. However, I still struggled like everyone else my age.
In high school I remember being around one guy who was "fooling around" and bragging about it. I remember talking to him and asking about the girl getting pregnant. He replied that "she could just get an abortion." I did not know what to say. I could not believe what I heard. I had been a part of a group from the church I attended at the time and saw a video on what a woman goes through during the process. This was a very conservative church. They separated male and females into two different parts of the building. I was in my late teens. I listened to a sermon that was very to the point. It was about lust that got carried away. There are consequences. The main problem within those relationships was that they were purely physical in nature. Maybe the heart and mind was a part. Unfortunately, there was no spiritual side.
The problem with so many relationships is that they never reach the "spiritual element." I had thought about putting "It is good, it is not so good" as the topic head. God looked down on Adam and Eve and said "It is Good." A true relationship is when God looks down between a man and woman and says "It is Good." Lust is not the good. I am not a perfect man. It is just that I have seen several marriages that were "It is not good." I have seen so many divorces. Some of them were in my own family and they did not help in producing positive images of marriage. (I have never married and the youngest.)
I deal with loneliness and lust like any man. However, I believe in Heaven and Hell and a Judgment Day. I also believe in "It is Good." I want more than just a physical or psychological or emotional relationship. I know what happens when a man and a woman never truly connect on the spiritual side. I have seen some really bitter breakups. I have heard "words" that are not my "Father's words." (I have used them in times of anger.) I have watched men and women lose that spiritual connection. It is not a pretty sight.
God is truly pleased when He looks down and sees a relationship wherein a man and woman truly connect in heart, mind, body, and Spirit. (I made a mistake in the past and wished I had done things differently. Two older, lonely people who start dating must pray together every time they get alone together.) God has to be at the center of the relationship and not the couple.
I could say more, but this thread is getting long. If a man and a woman never connect as God defines this connection within marriage they will never be truly happy. I want only what God wants for me. People, including myself, will not find true happiness unless God is at the center of the search and fulfillment of that search.
