" These four principles are worldview game changers. Mastery—your sex life will be shape by who or what rules your heart. Eternity—your sex life will be shaped by whether you live for the temporary pleasures of the here and now or with eternity in view. Unity—your sex life will be shaped either by bifurcating your life into the spiritual and secular or by acknowledging that all that makes up you has been united to Christ, and you take Christ wherever you go. Ownership—your sex life will be shaped either by acting as if your body belongs to you or by acknowledging that it has been purchased by God for his higher purpose. "
