To answer the question, one must have the three postulates in mind. The Bible is God’s Letter to Man. God is above us. God is our Beloved Father. We are His beloved children. One must believe that God is a God of love. The Bible says God is Love. God’s Nature is pure love. Hence, we follow what God tells us to do. We follow by faith as one would listen to a beloved earthly father.
God does not allow for homosexual behavior. God does not hate gay people. God does not allow for sex outside of marriage in the same way as God does not allow for sex between two men. Why would God prevent two people who love each other from being together? The same answer would be for the girl who wanted to have sex before marriage. God does everything out of love for us and care for our welfare.
A gay man may ask,” I love this man. What is wrong with my marrying him?” The answer would be the same for a heterosexual who wanted to have sex outside of marriage. We honor God with our bodies. We honor God with our lives. You may say that the whole thing seems foolish and antiquated. I agree. It does. A true believer in Jesus follows God out of love. It is not that hard when you love God with every fiber of your being. I hope I do not lose dear friends from writing this.
