There may be some in the Church, in the Christian community, who connect transsexualism or transgenderism with the seventh commandment, “You shall not commit adultery.” (See Exodus 20 or Deuteronomy 5.) They may see it as a form of sexual immorality. That could be the case, but, then again, it might not be.
Holding to the transgender lifestyle might rather be a case of breaking the first commandment, “You shall have no other gods before Me.” Or it might be an instance of breaking the second commandment, “You shall not make for yourself a carved image – any likeness of anything that is in heaven above, or that is in the earth beneath (for me, women), or that is in the water under the earth …” (I also had a thing for idolizing mermaids … fantasizing about being one.) Or it could be a matter of coveting, covered by the tenth commandment … coveting the body of a woman that you have seen … envy (Yep). Or it may be a matter of breaking a combination of the commandments. James chapter 2, says, that if we have failed in keeping one commandment, we have actually broken all of them, “For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all.”
Keeping the Law of God is not the means of our salvation. Christ has kept it for us. We are saved by grace alone, faith alone, Christ alone (see The Five Solas). The Apostle Paul, in Ephesians 2, expresses this well: “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.” We are not under a “covenant of works”, but the Law is a “rule of life” for us.
Paul the Apostle, in 2 Corinthians 6, says: “And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said: “I will dwell in them and walk among them. I will be their God, and they shall be My people.” Therefore, “Come out from among them and be separate, says the Lord. Do not touch what is unclean, and I will receive you. I will be a Father to you, and you shall be My sons and daughters, says the LORD Almighty.”
Yes, “Come out from among them and be separate …” In the first chapter of 1 Peter, we read, “But as He who called you is holy, you also be holy in all your conduct, because it is written, “Be holy, for I am holy.” “ Holy means “separate” or “set apart”. Set yourself apart from the world for Jesus.
