Revelation 2:5; Revelation 3:3; Revelation 3:19

5 Remember therefore from whence thou art fallen , and repent , and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent .
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.
19 As many as I love , I rebuke and chasten : be zealous therefore, and repent .
