Romans 1:26

Honestly, in your heart, what rules you? Who or what is your master? It should be Christ, but if you reject God then He will "give you up" to the god you choose. If the god you choose is your passions, you may find yourself involved in sexual (because that involves the most vulnerable part of who we are) relations completely opposed to the design God created in us. He designed a very specific way for us to relate sexually: 1 man + 1 woman united in marriage. Every sexual interaction different from that design is not of God and shows that God is not the lord of your passions. He will ONLY lead us to follow the pattern He has designed for us, NEVER 1 man + 1 man or 1 woman + 1 woman or 1 adult + 1 child or 1 married + 1 single or 1 single + 1 single. Each of these deviations from the Creator's design and all other deviations are clear indications that the Lord God, who created each of us, is not the one leading your life.
