Both the New and Old Testament of the Bible teaches it is wrong for a man to love another man in the same way a man loves a wife and wrong for a woman to love another women in the same way a wife loves a husband. Let's explore some of these teachings:
New Testament Teaching: "Who are the unrighteous that won't go to heaven? Fornicators, adulteries, men who love men." 1 Corinthians 6:9
This teaching is important because it clearly lists the acts/sins that if committed can prevent a person from entering into heaven when they die. Additionally, it teaches that homosexuality is just as bad a sin as having sex while not married or having sex with people other than your spouse. That said, good news is that anyone can receive forgiveness for any act/sin. The bad news is if you chose to commit these acts/sins because you believe they're not sins then you will die and go to hell because you never asked God's forgiveness for your act/sin.
New Testament: "God gave them up to vile affections so that men burned with lust for other men" Romans 1:26-27
This teaching is important because we are made to understand that God's Holy Spirit was removed from many of His people because the people's hearts were turned from God and toward pleasures of the flesh. Additionally, Romans 1:18-32 talks about ungodly people who call unrighteous truth and teach these lies to other people. One of the unrighteous acts that God says people teach as righteous/truth is that homosexuality is not a sin.
Old Testament: "Men should not sleep with other men as they would sleep with a women. This is an abomination to the Lord." Leviticus 18:22
This teaching is important because is clearly states that God views homosexuality as evil or an abomination.
A) "The Lord said I would not destroy Sodom & Gomorrah if there are at least 10 righteous people living in the city" Genesis 18:32
B) "The men of Sodom & Gomorrah said to Lot, bring the men out that visited you this day so we may have sex with them." Genesis 19:5
C) "The LORD rained upon Sodom and upon Gomorrah brimstone and fire out of heaven." Genesis 19:24
This teaching is important because this is one of the only times in the Bible where God clearly gives an example of what will happen to a person that refuses to repent of their sins... The cities were burned and turned into a hell on earth. More importantly, God shows the extent of His Love Mercy and Kindness because He says although thousands of unrighteous people live in Sodom & Gomorrah, if only 10 people would turn from their wick ways and repent I would spare the city from destruction. This is a message to all homosexuals, repent and pray forgiveness for you and the friend you know that live this lifestyle; by doing this God will forgive you and u will go to heaven to live with God forever. If God is willing to spare thousands for the sake of only 10 people asking forgiveness, then God will do a million times more in the life of the person asking forgiveness.
Are some people born with homosexual tendencies?
YES; Some people are born with homosexual tendencies but not because there exists a homosexual gene. To be absolutely clear, No gay gene exists. Some people are born with homosexual tendencies because from childhood they're pledged with a generational curse of homosexuality. A generational curse is when a demon responsible for a certain type of sin torments the members of a family for decades. For instance, if your Grandfather committed suicide then that same demon that tempted the grandfather will also tempt the father and the son to commit suicide. That said, if a little boy only 10 years of age is acting very effeminate or has even admitted to feeling sexual desires toward the same sex then the boy is in fact being tempted by a demon of homosexuality. If you're that child's parent then FEAR NOT. Your only response should be to show the child love, pray with him and read him the Bible so that he understands that it is wrong for a man to marry a man and wrong for a women to marry a women. ALWAYS remember the child's sin is no greater than yours and ALWAYS remember only God can Judge and ALWAYS remember only God can change people so NEVER NEVER NEVER get angry at your child for behaving effeminate and having feelings for the same sex. In time God will remove this demon from the child's life. It may take a day or last for years but never stop praying for your child even when he is an adult, and never fear for your child but have faith and believe that he will turn to God and all shall be well :)
"And the child's father said to Jesus, since a boy he has been possessed by this spirit; and Jesus replied, if you have faith the evil spirit will be removed and the father cried I have faith and Jesus healed his child." Mark 9:14-29
Can a person with homosexual sexual tendencies go to heaven?
YES; Homosexuality is an addiction the same as a porn addiction, sex addiction or alcohol addiction. Some addictions may be present with you all your life and sometimes you may fall but if at ALL times you look to heaven and tell God you love Him then ask mercy and forgiveness GOD WILL FORGIVE YOUR SIN AND REMEMBER IT NO MORE! NEVER LET ANYONE TELL YOU THAT BECAUSE YOU'RE STRUGGLING WITH THE ADDICTION OF HOMOSEXUALALITY YOU WILL GO TO HELL. NEVER LET ANYONE TELL YOU THAT HOMOSEXUALITY IS NOT A SIN! NEVER TELL YOURSELF THAT YOU'RE A BAD PERSON! ONLY GOD CAN JUDGE YOU AND GOD LOVES YOU TO DEATH!
The Homosexual movement is about love and God is Love, so why is homosexuality a sin?
Homosexuality is a sin because it is in direct defiance against the word of God; "In the beginning God made a man and a women and said let them be fruitful and multiply." Genesis 2:21-25 Homosexuality is a desire conceived by the devil that is in complete rebellion against God's will. This is why homosexuals were tempted by the devil to use the rainbow as a banner. The word of God says " I the Lord thy God will send a rainbow after every rain in remembrance of My promise to never again flood the earth because of mankind's wickness" Genesis 9:8-17
For homosexuals to use the rainbow to represent sin is to tell God who cares if you send another flood. To use the rainbow as a homosexual sign is in direct rebellion against God.
