We can come out of the world and separate ourselves unto God. The physical man lives in the world but spiritually we can live in the house of the Lord. The flesh needs food warmth and shelter and for that we go to work to earn the wherewithal and that is all the world can offer. We do not need television, filling our minds with the thoughts and deeds of those for whom Satan is god. We do not need to go to pubs, pop concerts, the cinema with all the violence. We are, or should be, a holy people. The early Church did not have all those distractions, but now we have those we have lost contact with the wonder-working God. No miracles, no nothing except a dead church and a lost people. We need to get back to God and be filled with His Spirit.I probably missed those posts. But you’re right, it can be more foundational that the way Jesus viewed the world.
It’s very difficult to be different than the world since the educational system is run by the world.
