When you pass through the waters, I will be with you; and through the rivers, they shall not overflow you: when you walk through the fire, you shall not be burned; neither shall the flame scorch you.
All Commentaries on Isaiah 43:2 Go To Isaiah 43
Gregory The Dialogist
AD 604
For the rivers overflow those whom the active business of this world confounds with perturbation of mind. But one who is sustained in mind by the grace of the Holy Spirit passes through the waters and yet is not swamped by the rivers, because in the midst of crowds of peoples he so proceeds along his way as not to sink the head of his mind beneath the active business of the world.
