Same-sex marriage is something very recent in terms of human history. Other than a few isolated cases of public same-sex unions through past centuries, same-sex marriage laws have only started appearing since 2001.

In the 1970s, gay activism was focused on the gaining of social acceptance for homosexuality.
The 70s thinking of marriage as a traditional institution that was contrary to the forward-thinking of homosexual acceptance changed by the end of the 80s. By the end of the 80s, seeking legal recognition of homosexual unions became part of the agenda.
Denmark was first country to legally recognize same-sex relationships by calling them "registered partnerships".

Starting with 2001, countries of the Western world started passing laws recognizing same-sex marriages.
From wikileaks1:
"In 2001, the Netherlands became the first country to permit same-sex marriages. Since then same-sex marriages have been permitted and mutually recognized by Belgium (2003), Spain (2005), Canada (2005), South Africa (2006), Norway (2009), Sweden (2009), Portugal (2010), Iceland (2010), Argentina (2010), Denmark (2012), Brazil (2013), France (2013), Uruguay (2013), New Zealand (2013), the United Kingdom (2014), Luxembourg (2015), the United States (2015), Ireland (2015), Colombia (2016) and Finland (2017). In Mexico, same-sex marriages are performed in a number of states and recognised in all thirty-one states. In Nepal, their recognition has been judicially mandated but not yet legislated."

God's Teachings differ and state that a marriage union is between man and woman.
Mark ch. 10: 6But from the beginning of the creation, God made them male and female. 7For this cause a man shall leave his father and mother; and shall cleave to his wife. 8And they two shall be in one flesh. Therefore now they are not two, but one flesh.2

Book of Truth prophecy:
"Not only do you have to witness sin, children, you then have to watch as sin is presented to you, where you are forced to accept it as being humane. I refer to one sin in particular, same sex marriage, which is presented as a natural right.
Sin is now presented in the world as a good thing.
As I have said before the world is back to front.
Good is presented as evil and those people who try to live by the Laws of God the Father, are sneered at.
Evil, no matter how you dress it up, cannot be turned into an act of goodness, in the Eyes of My Father."3

Important note for articles in 'society' category:
Articles in 'society' are not condemnation of any individual for it is not up to the reader, nor the chronicler to judge others. The articles chronicle recent societal changes for the reader's awareness with hopes the reader will reflect and make knowledgeable decisions in regards to his own life path.

There are millions of Christian-faith believers who have succumbed to a lethargy of their faith either by choice or lack of instruction from elders. They have discarded forever in favor of living for the moment by accepting secular laws that permit much which is contrary to their Christian beliefs.

If you believe in any way that you are more than "just a bunch of cells" then what becomes of 'you' after death of these cells? These government-enacted laws rule over their citizens while they are alive. Upon death, secular laws have no enforcement. What then? No matter how long your earthly life, eternity is a whole lot longer.

Please remember that forgiveness from God is available to anyone with genuine remorse who asks for forgiveness while alive, even on their last breath. After death, it is too late to seek forgiveness.
