22 You shall not lie with a male as with a woman. It is an abomination.
26 For this reason God gave them up to ovile passions. For even their 9women exchanged the natural use for what is against nature. 27 Likewise also the 1men, leaving the natural use of the 2woman, burned in their lust for one another, 1men with 1men committing what is shameful, and receiving in themselves the penalty of their error which was due.
28 And even as they did not like to retain God in their knowledge, God gave them over to a debased mind, to do those things pwhich are not fitting; 29 being filled with all unrighteousness, 3sexual immorality, wickedness, 4covetousness, 5maliciousness; full of envy, murder, strife, deceit, evil-mindedness; they arewhisperers, 30 backbiters, haters of God, violent, proud, boasters, inventors of evil things, disobedient to parents, 31 6undiscerning, untrustworthy, unloving,7unforgiving, unmerciful; 32 who, qknowing the righteous judgment of God, that those who practice such things rare deserving of death, not only do the same but also sapprove of those who practice them.
1 Timothy 1:9–10
9 knowing this: that the law is not made for a righteous person, but for the lawless and insubordinate, for the ungodly and for sinners, forthe unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, 10 for fornicators, for sodomites, for kidnappers, for liars, for perjurers, and if there is any other thing that is 3contrary to sound doctrine,
First of all, Jesus (who created us and therefore owns us and has the authority to determine right and wrong), as the God-man, did deal directly with the gay marriage issue, in the Bible’s New Testament, in Matthew 19:4–6: “And He answered and said to them, ‘Have you not read that He who made them at the beginning “made them male and female,” and said, “For this cause a man shall leave father and mother and shall cling to his wife, and the two of them shall be one flesh?” So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.’ ”
He could have continued:
Christ quoted directly from the book of Genesis (and its account of the creation of Adam and Eve as the first man and woman—the first marriage) as literal history, to explain the doctrine of marriage as being one man for one woman. Thus marriage cannot be a man and a man, or a woman and a woman.
Because Genesis is real history (as can be confirmed by observational science, incidentally), Jesus dealt quite directly with the gay marriage issue when he explained the doctrine of marriage.
Not only this, but in John 1 we read: “In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made” (KJV).
Because Jesus in a real sense wrote all of the Bible, whenever Scripture deals with marriage and/or the homosexual issue, Jesus himself is directly dealing with these issues.
Even in a secular context, the only answer a Christian should offer is this:
The Bible is the Word of our Creator, and Genesis is literal history. Its science and history can be trusted. Therefore, we have an absolute authority that determines marriage.
God made the first man and woman—the first marriage. Thus, marriage can only be a man and a woman because we are accountable to the One who made marriage in the first place.
And don’t forget—according to Scripture, one of the primary reasons for marriage is to produce godly offspring.11 Adam and Eve were told to be fruitful and multiply, but there’s no way a gay marriage can fulfill this command!
The battle against gay marriage will ultimately be lost (like the battle against abortion)unless the church and the culture return to the absolute authority beginning in Genesis. Then and only then will there be a true foundation for the correct doctrine of marriage—one man for one woman for life.
