The Scriptures were given to us for many good reasons. Among these, they reveal God’s promises to us, they give the lost and forsaken hope and comfort.
We are always safe to take the words of the scriptures and to so place them, that they can be made into our own personal petitions to God.
Psalm 91 is a wonderful example of this – see God’s promise and reassurance to us, see His guarantee; that He will never leave us or forsake us. He asks that we should believe, what He tells us and in doing so, we harness his promise of power in our lives.
