Heavenly Father, we come before You in the name of Jesus, lifting up our dear friend who is struggling with PTSD, nightmares, and anxiety. Lord, we ask for Your divine healing and peace to envelop them. Your Word says in Philippians 4:6-7, "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus." We claim this promise for our friend, asking that You replace their anxiety with Your peace and their nightmares with restful sleep. In Jesus' name, we pray. Amen.
