Book of Common Prayer

O God, by whom the meek are guided in judgment, and
 light riseth up in darkness for the godly: Grant us, in all
 our doubts and uncertainties, the grace to ask what Thou
 wouldest have us to do, that the Spirit of wisdom may save
 us from all false choices, and that in Thy light we may see
light, and in Thy straight path may not stumble; through 
Jesus Christ our Lord. Amen.
