'Have Faith' in the Bible

What is Apollos? Or what is Paul? Just servants through whom you came to have faith, as the Lord gave each of us opportunity.

And though I have the gift of prophecy, and am acquainted with all mysteries, and all knowledge: yea if I have faith, even. to remove mountains, and have not charity, I am nothing.

But now we still have faith, hope, love, these three; and the greatest of these is love.

For this reason tongues are for a sign, not to those who have faith, but to those who have not: but the prophet's word is for those who have faith, and not for the rest who have not.
