Bed involves prayers as well as sex. What I am in integrity before God is who I am in integrity with intimate others and public others. It is possible only by grace. No human being is this in her or his own strength. We are freed to the joyful responsibility of a life of integrity by God's saving grace.
Nothing is held back.
There can be no living two lives at once, one faithful and the other not. What one is before God one must be also for one's fellow human beings. Life in Jesus Christ is, from one moment to the next, from one relationship to the next, all of a piece. Integrity also has to do with the wholeness of the church. We have come to a point in this debate at which the church's integrity as a body is threatened.
