Take a good look at the Bible, both Old and New Testaments, and you will see that God was big on assimilation. What I mean by that is he expected anyone who wanted to join his congregation to be under one set of principles, rules, standards, or laws–his and his alone, whether it was the nation of Israel or the New Testament church. Why? Since he is the only true and living God and has proven that all his works are done in truth and righteousness (Psalm 19:9), he knows there are no higher standards to live by than his. Also, whenever he gives commandments, whether in the Old or New Testament, he assures us that they are so we will fear him in order to prolong our days “for our good always, that he might preserve us alive” (Deuteronomy 6:2, 24).
In other words, his intent (as I’ve stated so many times before) was for us to have eternal life that blesses us in this life and the life to come that we may prosper and be in health, even as our soul prospers (3 John 2). So when it came to strangers (foreigners) who wanted to live in Israel, Jehovah made it abundantly clear–
15 One ordinance shall be both for you of the congregation, and also for the stranger that sojourneth with you, an ordinance for ever in your generations: as ye are, so shall the stranger be before the Lord.16 One law and one manner shall be for you, and for the stranger that sojourneth with you. …29 Ye shall have one law for him that sinneth through ignorance, both for him that is born among the children of Israel, and for the stranger that sojourneth among them. Numbers 15
God knew this would be crucial for Israel’s survival as a nation according to the Deuteronomy scripture mentioned above. Sure enough, whenever Israel became weak as a nation later, it was because they wished to adopt the policies of the pagan nations around them or welcome pagans into their midst without requiring assimilation.
The same principle applies to his church. He wanted all congregations to be on the same page as him–
But as God hath distributed to every man, as the Lord hath called every one, so let him walk. And so ordain I in all churches. 1 Corinthians 7:17
For God is not the author of confusion, but of peace, as in all churches of the saints. 1 Corinthians 14:33
When they adopted the world’s mindset, that’s when they became spiritually weakened, such as Corinth and some of the churches mentioned in Revelation.
Europeans (and Americans, Canadians, Australians) are discovering, just like ancient Israel, that when you welcome people into your midst from Third World countries without pressuring them or demanding them to assimilate into a First World mentality, very bad things happen from physical and sexual abuse of women and children to terrorist attacks to human trafficking. Nevertheless, we see politicians and the Pope twisting God’s word to blackmail and extort various nations into taking on thousands of refugees, many of whom have no intent to contribute anything positive (like dumping the sharia mentality, holding down a steady job, or assimilating) to their host countries. It’s a recipe for disaster cooked up for the sake of global governance and one world religion, promoting the false idea that all ways of living are equal. It’s true we’re all created equal and in God’s image, but all images of gods aren’t equal. Neither are all mentalities. That’s the God’s honest truth taught from God’s holy, honest word.
