Read Song of Solomon 1
Focus on verse 2
I remember our boys response when they were younger and would happen to be around when their mom and dad were kissing each other. Typically the response was something to the effect of “eewww! Gross!” Though this expression was intended to be one of displeasure, there always seemed to be an underlying tone that made it clear they actually where glad their parents loved each other.
The love between a husband and wife is a beautiful thing when it is expressed as God designed it to be. I believe it is helpful for children to see that their parents love each other. It gives them a sense of security that the family is not in danger of breaking apart, and also demonstrates to them what a loving marriage should look like.
The Song of Solomon is almost entirely dedicated to describing the beauty and strength of romantic love between a man and a woman. It could also be interpreted as a metaphor of God’s love for His church. I personally believe that it is both. This is the book that proves that the Bible is not anti-sex in it’s teaching. It is actually very supportive of sex as long as it is within the context of marriage. As is the case with many other vises, the Bible clearly cautions against the abuse or misuse of sex particularly outside the bonds of marriage.
The only time when romantic affection between people genuinely gross is when it is abused in a way it was not meant to be used. God created humans as sexual beings knowing that we would take His gift and use it in ways He never intended. While this is disappointing to Him it is not surprising to Him.
When we misuse the gifts He gives us we reap the consequences of our disobedience, when we appropriately use the gifts He has given, we are blessed and He is pleased.
