Courage and Boldness of Holiness Preachers

Deut.31:6-8 "Be strong and of a good courage, fear not, nor be afraid of them: for the LORD thy God, he it is that doth goes with thee; he will not fail thee, nor forsake thee. 7 And Moses called unto Joshua and said unto him in the sight of all Israel, Be strong and of a good courage: for thou must go with this person unto the land which the LORD hath sworn unto their fathers to give them; and thou shalt cause them to inherit it. 8 And the LORD, he it is that doth goes before thee; he will be with thee, he will not fail thee, neither forsake thee: fear not, neither be dismayed".
