Hebrews 13:7-9

7Remember them that had the rule over you, men that spake unto you the word of God; and considering the issue of their life, imitate their faith. 8Jesus Christ is the same yesterday and to-day, yea and for ever. 9Be not carried away by divers and strange teachings: for it is good that the heart be established by grace; not by meats, wherein they that occupied themselves were not profited.
