Hello James, God be with you!
Please (all) permit a Protestant's reply on this faith issues board. I thought it might be for the good to hear a couple of the practical outcomes. Perhaps good to hear it first hand. (Lord Jesus Christ, Son of God, have mercy upon me, a sinner)
James, I'm sure you have considered the venereal disease and unwanted pregnancy aspect of this. One can attempt to protect themselves but none the less that concern is so very real. I would like you to know that it goes much further and deeper than that though. When I was your age I was very much of this world and, may God forgive me, could have cared less of this Christian law. I had a fair amount of premarital sex. You might not believe this but it is only A TEMPORARY pleasure yet carries with it LIFE LONG consequences! By the grace of God I did not contract disease nor do I bear an unwanted child. I should say 'to my knowledge' though. What if I do have a child in this world that I am not aware of?? What if one of the girls I had casual relations with had an abortion without my knowledge??? You see sin always takes us further than we want to go and carries consequences far greater than we are prepared for. I truly don't think that has happened mind you, but my point is it could be the case, and that is a simple fact I have to live with. As an Orthodox Christian you well know sex is God's blessing between a husband and wife. What about for me though? Imagine getting married, living with the woman you love, but as beautiful as God's gift is between us, how much of that glory has been contaminated or diminished because we had premarital sex before we met each other? All of this because I wanted a few moments temporary pleasure. God's will, plan, and rewards are so much greater than mine!
Also, in reference to your being 'normal' comment:
My wife and I were recently listening to an Orthodox sermon (liturgy) on line to which the priest made the point that 'to have a normal life' is the most common of prayers. He said it is also the worst prayer we could ever make. For we are not normal nor are we intended to be normal. We are partakers of The Divine Nature and to be 'normal' would make us partakers of the world. The world is consuming darkness and as you know The Divine is everlasting peace!
At your age I was one of those 'cool' kids, that was 'normal' and having all kinds of fun. Perhaps I was one of the ones that would tease you for being a virgin. Please know that you sir, as you stand right now, are far more of a man than I ever was back then!
Peace to you James! Be strong and meditate on God's living word.
