God is to be greatly feared. The gospel is not a soft, shallow thing. It is a solemn matter which has to do with time and eternity, life and death, eternal mercy and eternal judgment, salvation and damnation, Heaven and Hell.
Jesus said to His friends, His disciples,: “To you My friends I say: Do not be afraid of those who kill the body and after that can do no more. I will tell you Whom to fear; fear Him who, after He has killed, has the power to cast into Hell. Yes, I tell you, fear Him.” – Luke 12:4-5.
