Read this all through, I ask.

Homosexuality is a sin. It is wrong!

Leviticus 18:22 - "Thou shalt not lie with mankind, as with womankind: it is abomination."

Leviticus 20:13 - "If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them."

Romans 1:18-31 - "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;

19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.

20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:

21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.

22 Professing themselves to be wise, they became fools,

23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.

24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:

25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.

26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:

****

27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.

28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;

29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,

30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,

31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:"

1 Corinthians 6:9 - "Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,"

What God says is...God says that all homosexuals ["abusers of themselves with mankind"] will not enter into the Kingdom of God. Why because it is sin, and no sin can enter into Heaven.

Revelation 21:27 - "And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life."

Exodus 32:33 - "And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book."  Revelation 20:15 - "And whosoever was not found written in the book of life was cast into the lake of fire."

Romans 3:4 - "...let God be true, but every man a liar...."

Why do God's children tell Homosexuals they are "wrong"?

Ezekiel 3:18-21 - "When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand.  Yet if thou warn the wicked, and he turn not from his wickedness, nor from his wicked way, he shall die in his iniquity; but thou hast delivered thy soul.  Again, When a righteous man doth turn from his righteousness, and commit iniquity, and I lay a stumbling-block before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand.  Nevertheless if thou warn the righteous man, that the righteous sin not, and he doth not sin, he shall surely live, because he is warned; also thou hast delivered thy soul."

But there is hope.

Joel 2:32 - "And it shall come to pass, that whosoever shall call on the name of the LORD shall be delivered:"

1 John 5:11,12 - "And this is the record, that God hath given to us eternal life, and this life is in his Son. He that hath the Son hath life; and he that hath not the Son of God hath not life."

John 3:3 - "Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God."

John 3:16 - "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."

Just accept Jesus Christ as your saviour into your heart, and believe he is God come in the flesh and the son of God, which died upon the cross for your sins, by the atonement of his Blood cleasned you of your sin. Just ask, Romans 10:13 says paraphrasing, that whosoever shall call upon the name of the LORD shall be saved.

Romans 6:23 - "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord."

Jesus Christ can and will save you from the punishment of Hell and the Lake of Fire.

P.S. - About Sodom and Gomorrah.

Sodom and Gomorrah is (was) in sin.

Genesis 18:20 - "And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous; I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know."

Genesis 18:23 - "And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked?"  Lot, "the righteous" was saved and his family (Genesis 19:17-32, 29).

Genesis 19:1, the angels came to Sodom and met Lot.  They went to Lot's house (verse 2,3).

Genesis 19:4 - "But before they lay down, the men of the city, even the men of Sodom, compassed the house round, both old and young, all the people from every quarter:" The men came.

Genesis 19:5 - "And they called unto Lot, and said unto him, Where are the men which came in to thee this night? bring them out unto us, that we may know them."

The men wanted to have sex with the Angels and commit Sodomy.  "that we [the men] may know [have sex with] them [the angels]."

The words "may know" means sex, because in verse 7 and 8, Lot uses the same word.

Genesis 19:7,8 - "And said, I pray you, brethren, do not so wickedly.  Behold now, I have two daughters which have not known man; let me, I pray you, bring them out unto you, and do ye to them as is good in your eyes: only unto these men do nothing; for therefore came they under the shadow of my roof."

Verse 8, "not known man," that is to say, "not had sex with any man."  They [the men] don't want his daughters because they want the [male] Angels.

Lot was not being unhospitalable, and the situation had nothing to do with hospitality.  The Angels smitten the men because of their sin and wickedness.

Genesis 19:11 - "And they smote the men that were at the door of the house with blindness, both small and great: so that they wearied themselves to find the door."

God destroyed Sodom and Gomorrah because of their sin, especially because of the sin of homosexuality.

Genesis 19:13,15b - "For we will destroy this place, because the cry of them is waxen great before the face of the LORD; and the LORD hath sent us to destroy it... lest thou be consumed in the iniquity of the city."
