Redemption decisions

God’s deliverance is depicted by a mighty hand and outstretched arm.  Why not simply say mighty hand?  Wouldn’t that make the point of Divine supportive intervention sufficiently?  Perhaps the additional phrase outstretched arm holds deeper meaning.  Z’roa netuya in addition to being an outstretched arm can also be translated as an inclination to seed.  To be inclined to seed goodness, at any given time, in any given place, is how we live in God’s image.  At first glance, this anthropomorphic image seems historically remote.  Yet by this reading, the Image may be as near as our next (redemptive) decision.
