Why do those pastors keep attacking Rob Bell?

Pastors need to protect their sheep from anything that will pull them away from their shepherd, that is Jesus.  And sheep (us) are dumb, and keep wandering away from the flock, and their are A LOT of ideas floating around out their and A LOT of those ideas SOUND nice, but are not so nice.
It so happens that Rob Bell has some real issues at present that should NOT be absorbed in a believers life.
I quote from his book "Jesus Wants to Save Christians"
"For Paul, this goes all the way back to Genesis, to the creation of the world.  There is a new creation, one brought into being through the death of the old and the resurrection of the new, and everybody everywhere can be a part of it."  (Pg 106, Bell)
Unfortunately Paul does not agree with such a statement which you can see for yourself in Romans 8:28-30.  Paul does not use language of all-inclusive, rather inclusive language.
So how does this affect our faith, and our evangelism, and how can this be appealing to those who are lost?!
At the end of the chapter "Genital-Free Africans", on page 115 Bell says this as his closing statement:
"[Paul] 'welcomed all who came to see him.'
All.
That's who this Jesus is for.
Even soaking-wet genital-free Africans riding home in chariots."

But we cannot infer Christ' desires from Paul's desires.  We as the saved should welcome ALL who come to us for knowledge of our faith in Christ and why we have it, but that does not restrain or restrict God's judgement!  To believe that God has CHOSEN or elected the saved for all time allows room for God to be God, who is a God of grace and judgement.  To believe that all can be saved, should be saved, and will be saved is in fact degrading God, putting Him in a box, and limiting who He is!  So while we welcome all, we do so to find the elect that God has chosen before the foundations of the Earth.  So can we still welcome all, and God only choose many but not all?  Yes, to both.
