Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body – 1st Corinthians 6:18.
Fornication was once looked upon as a “No, No” for those who were professing to be Christians but down through the years both non-believer as well as believer look at it as something that needs to be and should be gratified rather its going against the Word of God. God nor His Word will never change, what He said, in the beginning, goes for then and now. People don’t want to mention it and turn their heads while people are dying and entering into hell because they didn’t adhere to the Word of God. God created the desire for both genders for the opposite gender with marriage. To have it without marriage is taking the forbidden fruit.
The secular world adapt to it because they live by the world standards and not God’s Word, but as a professing Christians unmartial sex is a sin against God’s Word (Know ye not that your body are the members of Christ? Shall I then take the members of Christ, and make them the members of a harlot? God forbid-1st Corinthians 6:15).
