The Difference Between Changing What You are and Who You are

Jeremiah 13:20-27
20 Lift up your eyes, and behold them that come from the north: where is the flock that was given thee, thy beautiful flock?

21 What wilt thou say when he shall punish thee? for thou hast taught them to be captains, and as chief over thee: shall not sorrows take thee, as a woman in travail?

22 And if thou say in thine heart, Wherefore come these things upon me? For the greatness of thine iniquity are thy skirts discovered, and thy heels made bare.

23 Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good, that are accustomed to do evil.

24 Therefore will I scatter them as the stubble that passeth away by the wind of the wilderness.

25 This is thy lot, the portion of thy measures from me, saith the Lord; because thou hast forgotten me, and trusted in falsehood.

26 Therefore will I discover thy skirts upon thy face, that thy shame may appear.

27 I have seen thine adulteries, and thy neighings, the lewdness of thy whoredom, and thine abominations on the hills in the fields. Woe unto thee, O Jerusalem! wilt thou not be made clean? when shall it once be?
