Psalm 121 tells us that God is with us. He never leaves us. He doesn’t reject us or tell us to go away. He is with us day and night to protect us and defend us. His angels have charge over us to keep us night and day. When we declare a scripture over our lives, it puts angels to work to bring it to pass. For example, when we say,” God heals all my diseases, by His stripes I am healed.” Angels go to work to bring that to pass. His word never loses power or comes back empty.
