Psalms 77:19

Thy way is in the sea -Probably the literal meaning here is, that God had shown his power and faithfulness in the sea (that is, the Red Sea), in delivering his people; it was there that his true character was seen, as possessing almighty power, and as being able to deliver his people. But this seems to have suggested, also, another idea - that the ways of God, in his providential dealings, were like walking through the sea, where no permanent track would be made, where the waves would close on the path, and where it would be impossible by any footprints to ascertain the way which he had taken. So in regard to his doings and his plans.
