But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.” ~ Isaiah 40:31 King James Version (a favorite of Aunt Norma’s when prepping for surgery)
In this Guideposts article, Bob Hostetler provides some Bible-based prayers for use when a person is fearful:
“The Lord is with you, mighty warrior” (Judges 6:12 NIV).
“When I am afraid, I put my trust in you” (Psalm 56:3 NIV).
“Don’t be afraid of a soul. I’ll be right there, looking after you” (Jeremiah 1:7-8 The Message).
“Peace I leave with you; My peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid” (John 14:27 NIV).
“Behold, God is my salvation; I will trust, and will not be afraid; for the Lord God is my strength and my song, and He has become my salvation” (Isaiah 12:2 ESV).
“I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord” (Romans 8:38-39 ESV).
“I sought the Lord, and He answered me; He delivered me from all my fears” (Psalm 34:4 NIV).
It’s not biblical, but this Traditional Scottish prayer is one of the author’s favorites:
From ghoulies and ghosties
And long-leggedy beasties
And things that go bump in the night,
Good Lord, deliver us!
