Is Cheating
Engaging in sexual relationships outside of the commitment of marriage will lead to many issues. There is a right way – a path – that should be taken in intimate relationships between a man and a woman. Fornication is taking shortcuts, with great detriment to both parties.
There are physical issues, such as pregnancy and subsequent children without security of both parents, leading to community/society issues. There is a tremendous risk of disease, some which are worse than AIDS. There is a mental complication (the sexual act is more than just a physical act, even with a prostitute, and it creates spiritual bonds that are not easily broken.) And there is a blow to a good reputation, especially for women, who are not treated kindly for being loose. But even loose men are not respected.
The world will promote it as normal, through its books, TV shows, and movies which all promote fornication without consequences.
It is not acceptable.
Fornicators will not inherit the Kingdom of God.
