I bet you find it funny to see a page titled sex on a church website. Well do you know who was the first person ever to declare, sex is good?
Well the answer I think might surprise you for it is God. Christians believe that it was God that made man and woman and 27 verses into the first chapter of the first book of the Bible, God says,
Be fruitful and increase in number. Genesis 1 v 27. God was telling Adam and Eve to have sex. Four verses later it says that, God saw all that He had made and it was very good. God was including sex in this.
Of course, God encourages us to understand that sex used in the wrong way can become bad, just like anything else really. That is why God calls us to keep sex within marriage. He says sex is best enjoyed that way.
