Fear at the Core

Is it fear at the core of our mistakes and suffering? Adam and Eve were afraid of being kept in the dark, then being found naked. It is fear thst bothers us every couple of minutes, "What if...?) It is fear that things will go terribly wrong in a situation or source of income that keeps me, and I hear many other people, thinking constantly until we are tired and sometimes bitter. 

If God is, as Jesus present him, a heavenly Father who gives good things to his children who ask, why do we fear? Who has more power than He? Or is it that we don't believe? What change could a person make to shift from unbelief to belief. That is a prayer for one person in scripture: "I believe. Help my unbelief!" Do we then pray for more faith. Those who pray must believe He exists and that He will reward those who trust in Him. Just praying, then, is an act of faith.

Being we are fallible, self-confidence isn't an error-free strategy. God confidence may be more psychologically powerful. How do we build more God confidence? Exposure to God? Praying, scripture, communion with other believers. Those make sense. 

How do you increase your God confidence?
