If you are trying to claim that God is too weak to preserve His Word in tact the way He claimed He would, then we are talking about 2 different Gods here. So yes, you are trying to disprove a strong God with your weak god based on the scientific method. Too bad for you however, because science has no place in disproving the spiritual realm. You are better of trying your hand at philosophical reasoning rather than science to do that.
“If you are trying to claim that God is too weak to preserve His Word...”
Please read the post—YOU (or whomever the original poster was) is projecting their weakness of faith.
