The SCOTUS decision can't possibly mean anything to Bible believing Christians. Nations come and go in history. The US is no different. One day it will no longer exist. That is reality. What some government decides about the definition of a certain word does not preempt God's Word. All of this debate is about money and people living outside of God's commands wanting acceptance. If every Christian denomination accepted gay marriage, it wouldn't change God's Word.
This whole issue is a lot about nothing. Why would you desire the agreement of a government that denies God's Word in so many other areas. Your enemies, often, define who you are more than your friends. If the masses want to give financial benefit to certain types of individuals based on who they have sex with, it is no concern of mine. It won't change my belief in God's Word, nor will it change what the Bible says about it. It certainly won't change the effects of such arrangements. Gravity is what it is. The more you try to prove it doesn't exist, the more you prove its existence.
Life will not end if the SCOTUS decides black is white and white is black. Lot was saved. We just need to focus on what matters, and it isn't black robe decisions.
