He had both male and female friends. When he meets with sexual frailty, he shows an immense compassion - witness the story of the Woman Taken In Adultery. There surely is no suggestion of negativeness toward sex on His part. He emphasizes that it is fidelity that is the hallmark of TRUE union and love. He shows that sexual uprightness is NOT merely a matter of external behavior, but is a matter of the heart.
Sexuality is sacred.
Sexuality is a matter of relationships. Sexuality is a matter of the heart, and not simply of behavior. It is an upright heart, a redeemed heart, a committed heart that enables a person to enter into and live within such a sanctifying relationship. The decisive factor in reshaping the Sixth Commandment for ourselves is the Resurrection of Jesus Christ. My strength is sufficient unto Thee.
