Revalation 3

3. Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
4. Thou hast a few names even in Sardis which have not defiled their garments; and they shall walk with me in white: for they are worthy.
5. He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
6. He that hath an ear, let him hear what the Spirit saith unto the churches.
