Is it your earnest desire to do all in your power to advance his cause and glory? Can you renounce every worldly object for Christ? If so, happy are you. But if not, your case is dreadful indeed.

This is a great quote!, If the christian is not willing to surrender every thing and every part of his life to Christ then the Lord will never be able to use that person to the fullest extent that He wants to.
