Thou Shalt be a Man and No God
Genesis 1:27 So God created man in his own image, in the image of God created he him; male and female created he them.
Creator God created people male and female. God determined the sex of each person. I am a man because God made me a man. Another is a woman because God made her a woman.
But today, the new worldly doctrine is that I, a man, may decide to become a woman. Doing so basically makes the statement that I myself am God. I can choose my own sex according to my own desires. In essence, saying or taking action to do such a thing is a statement overturning God's creative work and thereby creating myself anew all the while declaring I am my own creator.
Ezekiel 28:2 Son of man, say unto the prince of Tyrus, Thus saith the Lord GOD; Because thine heart is lifted up, and thou hast said, I am a God, I sit in the seat of God, in the midst of the seas; yet thou art a man, and not God, though thou set thine heart as the heart of God:
…
6 Therefore thus saith the Lord GOD; Because thou hast set thine heart as the heart of God;
7 Behold, therefore I will bring strangers upon thee, the terrible of the nations: and they shall draw their swords against the beauty of thy wisdom, and they shall defile thy brightness.
8 They shall bring thee down to the pit, and thou shalt die the deaths of them that are slain in the midst of the seas.
9 Wilt thou yet say before him that slayeth thee, I am God? but thou shalt be a man, and no God, in the hand of him that slayeth thee.
10 Thou shalt die the deaths of the uncircumcised by the hand of strangers: for I have spoken it, saith the Lord GOD.
