Moses was not frightened by the extraordinary phenomenon he saw before him. Neither was he hesitant or doubtful in his mind that this was a supernatural happening. It says in the next verse, that God called to Moses from within that burning bush as he got near. The Lord gives us visions…such wonderful and great concepts that are almost too much for our feeble minds to take in. But if we approach that vision with boldness and not doubt or fear…God will speak into our hearts…and extraordinary things will happen.
