How can i feel conclusion/relief/security/sur… on this belief?

This is the human condition-- We must live examined lives, and those who are people of faith must have an examined faith. Our lives, and thus are faith, must constantly be re-examined as well-- a unchanging faith is a dead faith. Those folk who believe they are "without faith" are probably wrong-- most folks "believe" in something (or just "believe" something) even if it is not "religion" as generally conceived. The same applies. The need to be "terrorized," as you put it, does not come from God as such, or at least uniquely to you, it comes from the fact of being human.
