Hebrews 13:7-9 NKJV
(7) Remember those who rule over you, who have spoken the word of God to you, whose faith follow, considering the outcome of their conduct. (8) Jesus Christ is the same yesterday, today, and forever. (9) Do not be carried about with various and strange doctrines. For it is good that the heart be established by grace, not with foods which have not profited those who have been occupied with them.
