Stumbling at the Word of God

Christ, made 'a stone of stumbling?'

Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded. Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner, And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.

That being said, in scripture does 'all' mean 'all' and 'world' mean 'world' as some would have us believe to be so?
