Revelation 3:2-3

New American Standard Bible

² Be constantly alert, and strengthen the things that remain, which were about to die; for I have not found your deeds completed in the sight of My God. ³ So ^(A)remember ^[a]what you have received and heard; and ^[b]keep it, and ^(B)repent. Then if you are not alert, ^(C)I will come ^(D)like a thief, and you will not know at ^(E)what hour I will come to you.
