No one person has the power to cause another's homosexuality. At worst, a parent-child relationship may be one factor in a whole complex group of influences. Despite media claims, homosexuality cannot be primarily genetic. But Christian counselors who specialize in this area of ministry have seen common life patterns in their counselees. These and other factors disrupt a person's security and sexual identity, and open the door to same-sex temptation.
Some people resolve their sense of guilt by revising their beliefs about homosexuality.
But the Bible consistently forbids sexual activity outside of a lifelong heterosexual commitment. So we must reject the pro-gay reinterpretations of Scripture. Avoiding the truth does not resolve guilt. Dealing with the truth of my son's reasons for getting involved in homosexuality has been a great challenge for me. I made many mistakes as a young single mother.
