And the two shall become one
No matter how much man desires to redefine marriage to fit their agenda, God laid out the reasoning for marriage. And it is impossible for two people of the same sex to ever meet that definition. Marriage is a joining with a possibility and probability of a living outcome. Science is something that those who promote gay marriage, continually complain that Christians deny. And yet here they are the ones perverting science in order that they may feed their desires.
Matthew 19:4-10 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 reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? “So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.”
See even science tells us that it takes a male and a female to produce. It takes a sperm from a male and and egg from a female to produce offspring. This is truly what a marriage is, the joining of a male and a female. It simply is impossible for two males or two females to produce offspring. Science can aid them, but the manipulation means it still needs both sexes.
So even if you deny the Christian explanation of marriage, you are not able to deny the scientific. Ironic isn’t it that the people who are always maligning Christians for their lack of appreciation for science now tell us that science does not matter, that love is the only basis for marriage regardless of the differences in sex.
