Just in case you get drawn into a discussion about the definition of marriage, Here is what the One, True, Most High, Living, Almighty God of the Bible has to say about it all!
Matt 19:4 He replied, Have you never read that He Who made them from the beginning made them male and female, 5 And said, For this reason a man shall leave his father and mother and shall be united firmly (joined inseparably) to his wife, and the two shall become one flesh? AMP
Lev 18:22 You shall not lie with a man as with a woman; it is an abomination. AMP
Lev 20:13 If a man lies with a male as if he were a woman, both men have committed an offense (something perverse, unnatural, abhorrent, and detestable); they shall surely be put to death; their blood shall be upon them. AMP
Rom 1:26 For this reason God gave them over and abandoned them to vile affections and degrading passions. For their women exchanged their natural function for an unnatural and abnormal one, 27 And the men also turned from natural relations with women and were set ablaze (burning out, consumed) with lust for one another — men committing shameful acts with men and suffering in their own bodies and personalities the inevitable consequences and penalty of their wrong-doing and going astray, which was [their] fitting retribution. AMP
1 Cor 6:9 Do you not know that the unrighteous and the wrongdoers will not inherit or have any share in the kingdom of God? Do not be deceived (misled): neither the impure and immoral, nor idolaters, nor adulterers, nor those who participate in homosexuality, 10 Nor cheats (swindlers and thieves), nor greedy graspers, nor drunkards, nor foulmouthed revilers and slanderers, nor extortioners and robbers will inherit or have any share in the kingdom of God. AMP
Jude 7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire. KJV
Don't ever feel that you have to convince someone. IF they want to know what God thinks, they WILL ask! If not, don't waste your time, energy and resources on it! Just be about your Father's business of preaching the Good News, healing the sick and working signs, wonders and miracles that WILL reach their hearts for HIM! AMEN! Here is Hillsong United with the new song "Relentless", because His love IS relentless for us! Let's be relentless in our pursuit of knowing Him! AMEN!
Shalom in Him!
