As humans, we tend to measure our potential response to threat or danger according to extremities. We spiral into Worst Case Scenarios, plotting outcomes for events that may never happen.
1 John 4:18 says that perfect love banishes the existence of fear. In other words, when we know and understand the love of God the Father, the Personification of Love who gave his Son to us as a gift of love, we come to experience the safety and protection that exists within love.
We are set free from the strain of fear, knowing that He who loves perfectly has already overcome the world.
There is no fear in love [dread does not exist], but full-grown (complete, perfect) love turns fear out of doors and expels every trace of terror! For fear brings with it the thought of punishment, and [so] he who is afraid has not reached the full maturity of love [is not yet grown into love’s complete perfection]. We love Him, because He first loved us.
1 John 4:18-19
