He cannot stand the lie, and will have nothing to do with it. Satan is that way about the truth. He cannot stand it, and is repulsed by it. If the people to whom you witness do not come to have faith, they will never be able to please God. And, if they do not please God, they do not stand a chance of getting into heaven.
Some people are good marketeers.
They can sell you practically anything because of their overpowering personality. But this is not the way it is when bringing people to faith. It comes through the vehicle of hearing. But faith does not come by simply hearing sounds. This is the proclamation of what Jesus accomplished in His death, resurrection, and return to heaven.
