His homosexual feelings are not going to change overnight. That will come with time, healing, and the care and concern of friends. Actively love that person. Words can be so empty. Demonstrate your caring by listening, by calling, by spending time, sitting together in church.
Love is a verb.
Listen with love and respond as you seek the counsel of Jesus. But love 'em where they're at. Don't be afraid to touch, hug, hold hands in prayer. We all need that physical affirmation of love from one another. Touching is not sexual, it's loving.
