…and the LORD caused the sea to go back by a strong east wind all that night, and made the sea into dry land, and the waters were divided. So the children of Israel went into the midst of the sea on the dry ground… – Exodus 14:21,22

Who shall say that God was not in the van of Israel when they went down into the sea? They could not see the ensign of His presence, but He could see their obedience to His bidding. How else did the sea in fright draw back? Was it not because the Lord rebuked the sea? The strong east wind did not of itself divide the sea; for a wind naturally strong enough for that would have blown all the people into the air. The wind was used of God to move the waters, but its chief object was to dry up the damp from the floor of the sea, and to make marching the more easy for the vast host of Israel. Truly the Lord was there, triumphing gloriously. No cloudy pillar was seen across the waters as Israel looked forward to the shore; but yet the Lord was there majestically; and you may have but little comfort of the Lord’s presence at this time, and yet God may be with you wondrously. Do not so much set your heart upon comfort but rejoice in the fact which gladdened Hagar in the wilderness: “Thou God seest me.” It does not matter to the fire whether the logs are cast upon it from the front, or the oil poured upon it secretly from behind the wall, so long as it finds its fuel. To you the daily supply of grace is more important than the supply of comfort, and this shall never fail you so long as you live.

Tried child of God, you have to bear your trouble, and when that is quite clear your way is no longer doubtful. Cast all your care on Him who careth for you, and in patience possess your soul. “Oh, but I thought I was going to find a way of escape made for me. “Listen!” God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.” You have to bear it, you see. Your great want for this present is faith in God, who has said-“I will bring again from Bashan, I will bring My people again from the depths of the sea.” ~ C.H. Spurgeon
