The world does not just speak to those outside of the “church” but also to those inside the church. Jesus was “hated” by many religious people inside the “church”. The more the “church” becomes like the “world” the more true Christians will be “hated” and “worldly Christians” will be loved.
John 15: 18-19 NASB 20
“If the world hates you, you know that it has hated Me before it hated you. If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, because of this the world hates you.”
