Our LORD created marriage with several specific purposes in mind. The creator/inventor knows the purpose of a "noun" [person, place, or thing], and requirements for it to operate well - over time. Guidelines must be in place. The same applies with marriage: Rules for benefits - otherwise, consequences.
Our LORD created male and female for multiplication, and the production of good-fruit. Generational-blessings is the objective, and seed must be involved = family. The family order is Man as the Husband - the head, accountable one, protector and seed for the future; the one with the power-of-authority.
The other half is Woman[womb/Female = ability to carry a fetus] as the Wife - anointed and gifted in many areas concerning the Family. Designed to receive - seed or vision; the one with the power-of-influence.
The big Parable is the Wheat and the Tares in the Gospels; one has to know this one to go forward in Understanding. The question in the Parable as well as now "Who has done this" with the answer being Satan! Satan also hates family and has his Children = Tares/Kenites working through Education, Economics, Politics, and Religion to destroy.
Gay Marriage is unacceptable in the Word, and to the LORD's Election. Those on the fence are uninformed and or those in jeopardy of losing tax exemption status from the #1 organization that redistributes wealth; and is foreign owned! I hear a Voice saying "come out of Babylon." The labor-pains of trouble, gets worse.
