But the patient expectance of Noah comes out strongly in the story, as well as the gradualness of God's working. Not till 'forty days'--a round number--after the land appeared, did He do anything. He waited quietly till the path was plain. Eager impatience does not become those who trust in God. It is not said that the raven was sent out to see if the waters were abated. No purpose is named, nor is it said that it returned at all. 'To and fro' may mean over the waste of waters, not back and forward to and from the ark. The raven, from its blackness, its habit of feeding on carrion, its fierceness, was a bird of ill-omen, and sending it forth has a grim suggestion that it would find food enough, and 'rest for the sole of its foot,' among the swollen corpses floating on the dark waters. The dove, on the other hand, is the emblem of gentleness, purity, and tenderness. She went forth, the very embodiment of meek hope that wings its way over dark and desolate scenes of calamity and judgment, and, though disappointed at first, patiently waits till the waters sink further, discerns the earliest signs of their drying up, and comes back to the sender with a report which is a prophecy: 'Your peace shall return to you again.' Happy they who send forth, not the raven, but the dove, from their patient hearts. Their gentle wishes come back with confirmation of their hopes, 'as doves to their windows.'
3. But Noah did not leave the ark, though 'the earth was dry.' God had 'shut him in,' and it must be God who brings him out. We have to take heed of precipitate departure from the place where He has fixed us. Like Israel in the desert, it must be 'at the commandment of the Lord' that we pitch the camp, and at the commandment of the Lord that we journey. Till He speaks we must remain, and as soon as He speaks we must remove. 'God spake unto Noah, saying, Go forth ... and Noah went forth.' Thus prompt must be our obedience. A sacrifice of gratitude is the fit close of each epoch in our lives, and the fit beginning of each new one. Before he thought of anything else, Noah built his altar. All our deeds should be set in a golden ring of thankfulness. So the past is hallowed, and the future secure of God's protection. It is no unworthy conception of God which underlies the strongly human expression that he 'smelled the sweet savour.' He delights in our offerings, and our trustful, grateful love is 'an odour of a sweet smell, a sacrifice acceptable' to Him. The pledge that He will not any more curse the ground for man's sake is occasioned by the sacrifice, but is grounded on what seems, at first sight, a reason for the very opposite conclusion. Man's evil heart the reason for God's forbearance? Yes, because it is _'evil from his youth_.' He deals with men as knowing our frame, the corruption of our nature, and the need that the tree should be made good before it can bring forth good fruit. Therefore He will not smite, but rather seek to draw to repentance by His goodness, and by the faithful continuance of His beneficence in the steadfast covenant of revolving seasons, 'filling our hearts with food and gladness.'
