For one thing.. God does not need man in order to prove his existance... and the lies of man do not disprove God, even if someone is trying to lie for God..
One thing I will say to the extent of people lieing for God.. how about the evolutionists tampering with evidence? Even the greatest scientists use the writings of others as factual and if the writing that they used as factual proves to be erronous then so to will there theory unless of course it is designed to go against the argument.. yeah it happens.
I sure hope that those Christians fix the erronous passage too.
And as to the comment on it bein ok to lie for God.. Outrageous!.. again God does not need man to prove him, there is proof enough.
