When a person makes a commitment to Christ, he or she must come into agreement with God that homosexual behavior is sin. That will come with time, the care and concern of friends, and the quality of his or her own continued surrender to Christ. Actively love that person. Words can be so empty. Demonstrate your love by listening, by calling, by confronting when necessary, by sitting together in church.
Love is a verb.
Listen with love and respond as you seek the counsel of Jesus. Love them where they're at. Don't be afraid to hug, touch, hold hands in prayer. We all need that physical affirmation of love from one another. Touching is not sexual, it's loving.
