Revelation 3:15-16, 20

I know all that you do, and I know that you are neither frozen in apathy nor fervent with passion. How I wish you were either one or the other! But because you are neither cold nor hot, but lukewarm, I am about to spit you from my mouth.

Behold, I’m standing at the door, knocking. If your heart is open to hear my voice and you open the door within, I will come in to you and feast with you, and you will feast with me.
