Remember and Repent

Revelation 2:5 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.

"The Christian life is a warfare against sin, Satan, the world, and the flesh. We must never yield to our spiritual enemies, and then we shall have a glorious triumph and reward." (Matthew Henry's Commentary)

Remember - to be mindful of, to remember, to call to mind

Repent - to change one's mind for better, heartily to amend with abhorrence of one's past sins
