You can believe in whatsoever you like, but the truth remains the truth, no matter how sweet the lie may taste.
A spirit ushered by false teachings is like a body nourished by sweets. The adult, as opposed to the child, will come to understand reasons one cannot live a healthy existence on nothing but candy; so likewise, the Christian must come to understand that one cannot know and love the will of God under false doctrine.
Heresy would like to think of itself as 'invented Truth'. But of course, all Reason and Logic would agree that no man can ever create Truth; he can only discover it. If heresy were ever at all beneficial, God would use it really to bring one right back to Truth, as countless 'inventions' have brought men to discovery.
What we fail to realize is we often become like Pharisees in our ruthless attempts to identify Pharisees (and impostors). While indeed some people use the old laws of religious pride to tear down men of God, others use the new laws of anti-religious anger to tear down men of God.
The urge to save humanity is almost always only a false-face for the urge to rule it. Power is what all messiahs really seek: not the chance to serve. This is true even of the pious brethren who carry the gospel to foreign parts.
Atheists are not the enemy; the real enemy knows Jesus Christ. Satan and all false prophets know very well that Jesus came from heaven, but still reject him. Matthew 10:36
Prophecy is True and Sacred and should never be mishandled by people who have no business speaking about Sacred Things in GOD'S Name.
A preacher shouldn't preach just to make you feel good. Then it's about the money not about the teach. He should preach the truth because the truth shall set you free.
The Word of GOD is Superior to the inferior words of men and the words of every false prophet and the teachings of every false religion.
