Psalm 91
A psalm of shelter under God's wings: no fear of terror by night or plague by day. Read honestly, it's a promise of God's protecting presence, not a guarantee that believers never suffer. Satan quotes verses 11-12 to Jesus to push Him to test God, and Jesus refuses (Matthew 4:6-7). God's last words promise "I will be with him in trouble," not that trouble won't come.
"When he calls out to Me, I will answer him; I will be with him in trouble. I will deliver him and honor him." (Psalm 91:15)
