I believe the abomination that causes desolation deals with Christians who try to prevent others from finding God and growing in their spiritual walk with the Lord...

Becuse well the only thing we are explicitly told in the bible about it is that it is
a) an abomination
and b) It causes desolation...

And well I know that whenever I need a prophetic word from God... I can't find a single Christain who is willing to help me with my quest...

In 5 years of asking for help... I could not find a single Christian who was willing to help me... they all thought I didn't deserve it...

This is how I came to the conclusion that I arrived at.
