Israel looked back because they were not yet committed to the One who was leading them to a better place.  Lot’s wife looked back because that was where her heart was. We tend to go in the direction we are looking.  We walk toward what is our focus.  Looking back destroys forward progress.  Look forward.  God has more for you to do.  Let Him open your vision to the good that lies ahead, then begin to face and walk in that direction.

Then the LORD said to Moses, “Why are you crying out to Me? Tell the sons of Israel to go forward.”  Exodus 14:15 (NASB)
