>>That seems like denying the power of God to change people.
Nope. Just recognizing the fallible and uninspired nature of those who assume dominion over the faith of others - usualy whilst perched upon the temple steps.
"...who, being themselves but fallible and uninspired men, have assumed dominion over the faith of others, setting up their own opinions and modes of thinking as the only true and infallible, and as such endeavoring to impose them on others, hath established and maintained false religions over the greatest part of the world, and through all time;...that it is time enough for the rightful purposes of civil government, for its officers to interfere when principles break out into overt acts against peace and good order; and finally, that truth is great and will prevail if left to herself, that she is the proper and sufficient antagonist to error, and has nothing to fear from the conflict, unless by human interposition disarmed of her natural weapons, free argument and debate, errors ceasing to be dangerous when it is permitted freely to contradict them.

--Thomas Jefferson, 1786
