Dobson believes that God defines marriage as between one man and one woman only and describes this as the central stabilizing institution of society. Dobson believes that any sexual activity outside of such a union—including homosexuality—cannot be approved by God. In Dobson's view, homosexuality results from influences in a child's environment rather than an inborn trait. He states that homosexual behavior, specifically "unwanted same-sex attraction", has been and can be "overcome" through understanding developmental models for homosexuality and choosing to heal the complex developmental issues which led to same-sex attraction.
