Now as far as same sex marriage, it’s not even in the Bible, but here is something for you to consider, “Thou shalt not lie with mankind, as with womankind; it is abomination.” (Leviticus 18:22)
“Therefore shall a man leave his father and his mother, and shall cleave unto his wife; and they shall be one flesh” (Genesis 2:24)
But the god of this world hath blinded the minds of them that obey not the truth. They say you can do whatsoever pleases you; I beg to differ, I believe marriage will only work if two people give up their self for the greater cause. “Can two walk together, except they be agreed?” (Amos 3:3) So learn to agree with each other and not argue.
“And if a house be divided against itself, that house cannot stand.”(Mark 3:25) This is where Satan comes in to divide and conquer.
