Joel Osteen is a false prophet by his own testimony on the Larry King show (on CNN).  Read the transripts and find out for yourself.  He said he wasn't sure how Muslims and Jews would be saved.  He also said he doesn't like to preach on sin.  Jesus said He is the only way to the Father and eternal life.  Jesus is the only one who can remove God's wrath from us and unite us with God.  Without preaching on sin (fallen man) and the forgiveness that Jesus gives, there is NO point in preaching.
