'Have Faith' in the Bible

"Because of your little faith," he answered. "In solemn truth I tell you that if you have faith the size of a mustard-seed, you can say to this mountain, 'Move from this place to that!' and it will move; and nothing will be impossible to you.

In reply Jesus said to them, "In solemn truth I tell you that if you have faith and never doubt, you will not only do what has been done to the fig tree, but even if you say to this mountain, 'Up, cast yourself into the sea!' it shall be done;

but the Scripture has shut up the whole world in prison together under sin, in order that the promise due to faith in Jesus Christ might be given to those who have faith.

This saying is trustworthy. On this I want you to firmly insist; that those who have faith in God must be careful to maintain honest occupations. Such counsels are good and profitable for men.

Some one indeed may say, "You have faith, and I have deeds." "Then show me your faith," I answer, "apart from any deeds, and I will show you my faith by my deeds."
