I have begun to suspect that any sexual activity that is contrary to God’s law will bring curses for some number of generations. We must overcome these things before we finish this life.

The number one reason we have found for the sinful sexual activity of our day is that proper love relationships are not shown in the home.
In many homes, even Christian homes, the proper relationships are not lived.
