AbideinHim
Just like we protect our computers from viruses with a fire wall. Know that we that are in Christ have a mighty fire wall of protection. For He is our hiding place, our refuge and our strength, and He is a mighty shield of protection to all those that dwell in the secret place of the most high and put their trust in Him.
"But you, LORD, are a shield around me, my glory, the One who lifts my head high.” (Psalm 3:3)
