Is Fear an Absolute in Our Nature?

Is it in our nature to fear or not to fear? I was watching a movie scene where a person ran across a room while  machine guns bullets tore across it in sync. What makes a person believe they can outrun a deadly shower like that?

Then I thought with God, there is no fear just absolute confidence in success. But how does one obtain that level of confidence when by nature, humans know fear, are comfortable with it and expect Its companionship into the unknown?

But do we always have to expect it? Is fear an illusion, one of the many false conditionings taught by humans for humans that are absorbed into their subconscious? Is fear a part of our nature anymore after we are reborn with the nature of God’s living within us?

Like with any learned negativity, a process of unlearning is required. Can we reprogram a very prominent and specific characteristic that is embedded in every fiber of our being into a permanent hibernation? Even though fear can be conquered, the fact remains It is there to be conquered. How does one eliminate Its root so the process of conquering is eliminated rendering void every particle of fear itself?

Is it like with the sudden urge to vomit when you try everything to squash the urge, push it down in order to rise above the nausea and proceed onward obstructed? How to squash the urge?How to eliminate its entire concept?

When we are reborn every positive characteristic strength is available for utilization. Every form of weakness becomes defeatable. The question is how and can it be as simple as understanding weakness is no longer an option that is to be felt and pondered over?

I believe it is, when clothed in the full Armour of God.
