As a theist, the internet is a huge blessing. Since many atheists (well the ones I have met online which is a rather small yet vocal subset of atheists; the ones offline I have met in person have been quite intelligent) focus on the websites with little academic validity...if that is all a nonbeliever is exposed to, it makes the job of converting them to a particular faith much easier. If theists can beat you at your own game, then you have nothing.
But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin.
