The main issue is their relationship with God, not their sexuality. You may need extra grace, forbearance and persistence to build relationship with your friend. In response, they may develop a protective shell or push people away - anticipating future rejection. Many men and women with same-sex attractions have been wounded - by family members, peers and sometimes by Christians. Would you want to develop relationships with those people? Would you want to follow a God like the one they’re displaying? Or imagine attending church and hearing derogatory language from the pulpit. Imagine attending a gay pride parade and hearing insults shouted by church people standing on the sidelines. Many of those involved in homosexuality have been wounded by well-meaning but ignorant Christians.
Rather than seeing your friend as a homosexual, think of him or her as a person who struggles with sexual brokenness/sexual wholeness. Look beyond the “gay” or “lesbian” label to the whole person inside. Your friend is a man or woman with complex fears, hopes and needs. The answer is simple: The same way you share God’s truth with anyone else. We are often asked, “How do I witness to this person?” Many of us know someone who identifies as gay, lesbian or bisexual, whether a co-worker, neighbor, or friend.
