God speaks through His servants. Dr. A.W. Tozer was a servant of God! Pause and consider his words! They are as applicable today as the day he spoke them!
This quiet religion that apologizes: “I haven’‘t anything to say” does not square with the vision of the heavenly beings who say with their voices, “Holy, holy, holy!”-- A.W. Tozer
You may say: “Well, I worship God in my heart.”
I wonder if you do. I wonder if you are simply excusing the fact that you have not generated enough spiritual heat to get your mouth open!
