Revelation 3:3-5

3So remember what you received and heard. Obey, and change the way you think and act. If you’re not alert, I’ll come like a thief. You don’t know when I will come.

4But you have a few people in Sardis who have kept their clothes clean. They will walk with me in white clothes because they deserve it.

5Everyone who wins the victory this way will wear white clothes. I will never erase their names from the Book of Life. I will acknowledge them in the presence of my Father and his angels.
