It's about Worship not just a Relationship with our Creator.

Quote
Zechariah says that in the Millennium all nations will come up to Jerusalem for the Feast of Tabernacles, and any nation that does not will incur God's punishment.
Zechariah 14:16-19


That is NOT just about a relationship no matter how warm and fuzzy that sounds.
And besides whatever it will be called then..
Right now in any dictionary or definition of the word it's called a "Religion."
So one can't hate religion and love God because God will call for Worship and Worshiping a God IS called a Religion at this time.
So that's why it can be very confusing to others the Hate word.
