'Same Spirit' in the Bible

The same spirit certifieth our spirit that we are the sons of God.

To one is given, through the spirit, the utterance of wisdom; to another is given the utterance of knowledge by the same spirit;

to another is given faith, by the same spirit; to another the gifts of healing, by the same spirit;

and these all worketh even the self same spirit, dividing to every man several gifts even as he will.

Seeing then that we have the same spirit of faith, according as it is written - "I believed and therefore have I spoken" - we also believe, and therefore speak.
