'Able to Save' in the Bible

Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.

What is the profit, my brethren, if faith, any one may speak of having, and works he may not have? is that faith able to save him?

There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?
