"If I kiss my girlfriend, is that considered as a sin?"
Assuming that our common point of reference is the Bible, let’s see what the Bible says:
"- – -anyone who looks at a woman lustfully has already committed adultery with her in his heart." Matthew 5:27-28 (notice the last word, "his heart" – Key word)
When a man looks at a woman he is not married to, he thinks about taking her clothes off and imagining her naked body and – – – (that is a short overview of lust in man’s brain, let me save you from the detail).
When a man lets his eyes wonder off and his heart and mind follow, the man is considered "adulterer" according to the Bible because the damage of sin has already been done to the soul (heart) of that person. Sin of adultery has already been committed at a spiritual realm, a realm you and I are called to know and worship God (John 4:24). (BTW, this is the main difference between the Old and the New Testament Law!)
Remember, the man didn’t even touch the woman when he is held responsible for a sin of adultery.
If seeing a woman lustfully is considered as “adultery” (dangerous sin which has a potential to wreck one’s future), how do you think exchanging saliva with a woman a man is not married to through kissing is considered as? As “holiness" or as “a different face of adultery?" I leave that question for you.
Remember, the issue here is not the actual pre-marital sex but the condition of the heart and mind of a person because one’s body is like a “robot.” It does what the heart and mind of the person instruct it to do so.
What does a man think when he kisses a girl he is not married to? How wonderful Matthew 5:27-28 verses are??? Or something else?
I leave that question for you too.
BTW, when a man kisses his woman, a woman he is married to, what goes on in his mind is not Matthew 5:27-28 but images of his wife’s naked body and how exciting the sex is going to be (and more, again I save you from the detail). And, that kind of thinking and imagining, my dear, is like a holy worship. Do you know why? Because it is the will and word of God for the man to be consummated in sexual intimacy with one woman he is married to. When the two become one, their sexual intimacy gets decorated by God’s presence. God’s presence in turn makes their sexual union pure and honorable (Hebrews 13:4) and fulfilling and pleasurable more than you can ever think or imagine (Song of Solomon 3).
This being so, don’t you think “Is kissing a sin” kind of question is nothing but baloney? ///
