1. Illicit sex leads to other sins

    As soon as there will be contamination of illicit sex life, he will be bereft of all good character, this basic principle. And the whole world is now encouraged in that way. So how we can expect good character from the modern man?

    If you indulge in illicit sex life and naturally other things, intoxication, gambling, then there will be no limit of expenditure. And to meet all those expenditure one has to adopt cheating or stealing.
