2 Bible Verses about Revival, Corporate

Remember, therefore, from what you are fallen, and reform, and do the first works, otherwise I will come to you quickly, and take away your lamp out of its place, unless you reform.

Be watchful, and strengthen the things which remain, which are ready to die: for I have not found your works filled up in the sight of God. Remember, therefore, how you have received and heard, and hold fast, and reform: therefore, unless you are watchful, I will come upon you as thief, and you shall not know what hour I will come upon you.
