Why can't gays be Christian? We're all sinners. And Jesus died to take take away our sins. So as long as gays believe in Jesus, they're pretty much saved, right?
God established the original and
only standard for a sexual relationship at Genesis 2. After having created the first man Adam, God then said: "It is not good for the man to continue by himself. I am going to make a helper for him, as a complement of him.”(Gen 2:18) Therefore, "Jehovah God had a deep sleep fall upon the man and, while he was sleeping, he took one of his ribs and then closed up the flesh over its place. And Jehovah God proceeded to build the rib that he had taken from the man into a woman and to bring her to the man."(Gen 2:21, 22)
These were told by Jehovah God: "Be fruitful and become many and fill the earth and subdue it, and have in subjection the fish of the sea and the flying creatures of the heavens and every living creature that is moving upon the earth.”(Gen 1:26)
Hence,
only a man and a woman are to be bound together in marriage, and only in this arrangement is a sexual desire to be fulfilled, and possibly children. This marital arrangement, when implemented as God purposed it, becomes a stable and fulfilling union. This gives a firmness and stability for any children born of this union, having both a loving father and mother.
Any other union, such as a man and a man, or a woman and a woman,
violates this original marital union, and comes under the heading of fornication (Greek
porneia, from which the English word pornography comes), meaning "Illicit sex relations outside of Scriptural marriage." Bauer’s
Greek-English Lexicon of the New Testament (revised by F. W. Gingrich and F. Danker, 1979, p. 693) defines
por·nei´a as “prostitution, unchastity, fornication, of every kind of unlawful sexual intercourse.”
The apostle Paul wrote: "For this is what God wills, the sanctifying of you, that you
abstain from fornication; that each one of you should know how to
get possession of his own vessel in
sanctification and honor, not in
covetous sexual appetite such as also those nations have which
do not know God."(1 Thess 4:3-5)
Jesus told the Pharisees: "Did you not read that he who created them from the beginning made them
male and female and said, ‘For this reason
a man will leave his father and his mother and will stick to
his wife, and the two will be
one flesh’? So that they are no longer two, but one flesh. Therefore, what God has yoked together let no man put apart.”(Matt 19:4-6)
Hence, Jesus said that only a "male and female" are to be linked in matrimony, for he further said to the Pharisees, when asked about divorce under the Mosaic Law: "Moses, out of regard for your hardheartedness, made the concession to you of divorcing your wives, but such has not been the case from the beginning. I say to you that whoever divorces his wife, except on the ground of fornication, and marries another commits adultery.”(Matt 19:8, 9)
Therefore, any marital union other than "male and female" is a violation of God's original marital arrangement and will receive God's wrath, for Jesus said that "he that exercises faith in the Son has everlasting life; he that
disobeys the Son (by forming an unnatural marital union) will not see life, but the
wrath of God remains upon him."(John 3:36)
