Summary: Just because someone is a homosexual does not mean that we cannot love him (or her) or pray for him (her). Homosexuality is a sin and like any other sin, it needs to be dealt with in the only way possible. It needs to be laid at the cross and repented of.
The Bible, as God's word, reveals God's moral character and it shapes the morality of the Christian. The Bible has much to say about homosexuality:
1. Lev. 18:22 , "You shall not lie with a male as one lies with a female; it is an abomination."
2. Lev. 20:13, "If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act; they shall surely be put to death. Their bloodguiltness is upon them."
3. 1 Cor. 6:9-10, "Or do you not know that the unrighteous shall not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals,1 10nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, shall inherit the kingdom of God."
4. Rom. 1:26-28, "For this reason God gave them over to degrading passions; for their women exchanged the natural function for that which is unnatural, 27and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, men with men committing indecent acts and receiving in their own persons the due penalty of their error. 28And just as they did not see fit to acknowledge God any longer, God gave them over to a depraved mind, to do those things which are not proper."
With such clear statements against homosexuality, it is difficult to see how different groups can say the Bible supports homosexuality. But they try by redefining love, marriage, sex, homosexuality, etc. in order to accomplish their goal. But the truth is that God created man and woman, not man and man, or woman and woman. Nevertheless, the Bible is a powerful book, and because it is the homosexuals often try and make the Bible agree with its agenda. But it doesn't work. The Bible does not support homosexuality, as we have seen from the scriptures above.
Unlike other sins, this sexual sin has a judgment administered by God Himself: He gives them over to their passions (Rom. 1:26-28). This means that their hearts are allowed to be hardened by their sins. As a result, they can no longer see the error of what they are doing. Without an awareness of their sinfulness, there will be no repentance. Without repentance, there will be no forgiveness. Without forgiveness, there is no salvation.
Should homosexuals be allowed to marry one another?
In this politically correct climate that relinquishes morality to the relativistic whims of society, stating that homosexuals should not marry is becoming unpopular. Should a woman be allowed to marry another woman? Should a man be allowed to marry another man? Should they be given legal protection and special rights to practice their homosexuality? No, they should not.
The Bible, of course, condemns homosexuality. It takes no leap of logic to discern that homosexual marriage is also condemned. But our society does not rely on the Bible for its moral truth. Instead, it relies on humanistic and relativistic morals upon which it builds its ethical structure.
Homosexuality is not natural. Just look at the male and female bodies. They are obviously designed to couple. The natural design is apparent. It is not natural to couple male with male and female with female. It would be like trying to fit two screws together or two nuts together and then say, "See, its natural for them to go together."
