The idea of Jesus coming at any moment used to fill me with fear. I was worried that He would show up right after I had done some terrible thing or thought some terrible thought or had some terrible motive in my heart and that I would be lost. Those fears were completely unfounded.

Looking into this doorlike opening into the spiritual realm, John heard the same trumpet-like voice he had heard in Revelation 1:10. The voice of the Lord Jesus. He is called to come up to the very throne room of God.
