In fact, the great part of our life has to be spent under these conditions, and we need to hold some well-ascertained principle regarding God's dealings, if our faith is to survive. And here in God's treatment of Noah we see that God may as certainly be working for us when not working directly upon us, as when His presence is palpable. His absence from us is as needful as His presence. The clouds are as requisite for our salvation as the sunny sky. When therefore we find that salvation from sin is a much slower and more anxious matter than we once expected it to be, we are not to suppose that God is not hearing our prayers. When Noah day by day cried to God for relief, and yet night after night found himself "cribb'd, cabin'd, and confined," with no sign from God but such as faith could apprehend, depend upon it he had very different feelings from those with which he first stepped into the ark. And when we are left to one monotonous rut of duty and to an unchanging and dry form of devotion, when we are called to learn to live by faith not by sight, to learn that God's purposes with us are spiritual, and that slow and difficult growth in self-command and holiness is the best proof that He hears our prayers, we must strive to believe that this also is a needful part of our salvation; and we must especially be on our guard against supposing that as God has ceased to disclose Himself to us, and so to make faith easy, we may cease to disclose ourselves to Him. For this is the natural and very frequent result of such an experience. Discouraged by the obscurity of God's ways and the difficulty of believing when the mind is not sustained by success or by new thoughts or manifest tokens of God's presence, we naturally cease to look for any clear signs of God's concernment about our state, and rest from all anxious craving to know God's will about us. To this temptation the majority of Christian people yield, and allow themselves to become indifferent to spiritual truth and increasingly interested in the non-mysterious facts of the present world, attending to present duties in a mechanical way, seeing that their families have enough to eat and that all in their little ark are provided for. But to this temptation Noah did not yield. Though to all appearance abandoned by God, he did what he could to ascertain what was beyond his immediate sight and present experience. He sent out his raven and his dove. Not satisfied with his first enquiry by the raven, which could flit from one piece of floating garbage to another, he sent out the dove, and continued to do so at intervals of seven days.
