I’m going to get disagreement with this post, but it is nonetheless biblical. God says that true Christians must never become too close with the ways of the world, because these are contrary to the ways of God:
“Ye adulterers and adulteresses, know you not that the friendship of the world is enmity with God? Whosoever therefore will be a friend of the world is the enemy of God” (Jam. 4:4).
Getting too friendly with the sins around us is demonstrating hatred against God, and it is a visible fruit that this person is NOT a true Christian. God has explicit instructions in the Bible for Christians, which must be followed for their own good. Rejecting these is willfully rejecting their marriage vows and trampling on their marriage covenant. In this light, it is easy to see why God calls these people His enemies.
How does the true Christian become too friendly with the world? By rejecting the “royal law” of James 2:8. By doing this they show that they are unworthy of being God’s royalty and noble Christian ambassadors. Christ calls the true (obedient) Christians his bride. Is this a calling more enticing than what the world offers? Of course it is – a trillions times more. And it is eternal and spiritual, rather than temporary and mortal.
