Revelation 2:4-5

4But I have something to say against you. You loved me very much when you first believed in me. You do not love me as much now.

5Think carefully about this! You do not now live in the way you did at the beginning. So you must change the way you live. Do again the good things that you did at the beginning. If you do not change the way you live, I will come to punish you. I will take away your lampstand from its place.
