Good answers all. Anyone who visits Jerusalem and sees the wall around the old city will see the gate in the wall called in ancient times, “the eye of the needle.” The eye of the Needle was a very low gate, a man could walk through it, but a camel would have to have anything he was carrying removed from his back, get down on his knees and creep through it in an uncomfortable, position with his head bowed down. Not something camels enjoied but sometimes had to do when the other gates where closed for one reason or another.

So too anyone attached to things of this world, money, property, pride, etc anyone who has places his worth on things of this world will not be barred from heaven, if they can humble themselves before God, do what He requires of us lay down anything that comes before God and His will, and get humble ourselves.
