God created your body to completely trust Him in mind, body and spirit. However, after the fall, sin entered, causing us all to mistrust people in the world. Violence, abuse, and other sins made people grow fearful of the world around them.
Your body gives off a physical response when your brain believes or perceives a threatening situation. An increase in adrenaline occurs, making the brain choose to either fight the situation or flee from it.
Anytime you feel emotional, mental, or physical pain or other trauma, this causes you to be fearful. Yet, even in those moments, God calls you to trust in Him, rather than in what you can see.
The moments when you cannot see or feel God are prime times to experience fear, yet God promises he can overcome fear.
