When the children of Israel came up out of the land of Egypt, we read that God "led them about through the wilderness by the Red Sea." Being overtaken by Pharaoh and his host, who pursued in order to bring them again into bondage, they were sore afraid.
With the enemy behind, and the sea before them, their situation was a fearful one. What could they do? To return was to go into slavery again—to go on seemed equally impossible. Upbraiding him who had led them out of the land of their captivity, they were told to "stand still and see the salvation of the Lord." Presently came the voice of God, saying, "Speak unto the children of Israel that they go forward." Again, at God's command, Moses stretched forth his rod, and the waters parted and became a wall on either side of them, and they went through on dry land.
The command "go forward" comes with equal force to all who have fled from the bondage of sense, and are striving to gain the perfect liberty of the children of God.
