The word "forever" is used numerous times in the Bible for things that have ceased or ended. I would be very cautious in hinging my beliefs upon that word. You may want to study that word further.
To be honest, to many churches, removing the teaching of eternal burning hell removes the method they use to motivate people, which is sad. These misguided people don't realize the true character of God and are unable to use His loving mercy to entice others but resort to a method of using fear of eternal torment instead.
