From Eugene H. Peterson’s Praying With the Psalms:
I call upon you, O LORD; come quickly to me; give ear to my voice when I call to you! ~ Psalm 141:1
Arrow prayers — petitions shot off to God on the spur of the moment — are spontaneous and urgent. The use of incense to symbolize prayer and the appointing of an evening hour for the sacrificial act of worship are legitimate enough, but prayer cannot be confined to such established forms and set times. Empty hands and unstudied words are always welcome before God.
PRAYER: Lord, take the half-formed sentences I address to you and the half-concious movements I make toward you — my interjections and my gestures — and make prayers of petition and praise out of them, in the name of and for the sake of Jesus Christ. Amen.
