I have found being in a love relationship with God the Father,Son and Holy Spiriit brought a whole new definiton to fear. I finally found someone who put that into words for me. I have been reading John Bevere's book "Driven by Eternity". He brought clarity to many areas of my faith in this book. The most impactful so far for me was his definition of rightous fear of God. Rightous fear of God is the fear of being away from him. In John 17:3 , Now this is eternal life; that you know, the only true God and Jesus, The Christ whom He sent.
That knowing is a close contious intimacy dear to your heart that you don't want to be far from.
