When we become children of God, through faith in Jesus Christ, He becomes the wall that shields us from the enemy of our souls.
To dwell in God’s shelter, we have to first place our trust in Jesus Christ. Shelter is a place where we find safety and security. The phrase “the shadow of the Almighty” means that for His shadow to hit us, we have to be right next to Him. That is done by drawing near to Him through praying, reading, and living out the Scriptures.
