Here we have, then, as the first thing needed, God's loving compulsion to effort. To 'stir up the nest' means to make a man uncomfortable where he is;--sometimes by the prickings of his conscience, which are often the voices of God's Spirit; sometimes by changes of circumstances, either for the better or for the worse; and oftentimes by sorrows. The straw is pulled out of the nest, and it is not so comfortable to lie in; or a bit of it develops a sharp point that runs into the half-feathered skin, and makes the fledgling glad to come forth into the air. We all shrink from change. What should we do if we had it not? We should stiffen into habits that would dwarf and weaken us. We all recoil from storms. What should we do if we had them not? Sea and air would stagnate, and become heavy and putrid and pestilential, if it were not for the wild west wind and the hurtling storms. So all our changes, instead of being whimpered over, and all our sorrows, instead of being taken reluctantly, should be recognised as being what they are, loving summonses to effort. Then their pressure would be modified, and their blessing would be secured when their purpose was served. But the training of the father-eagle is not confined to stirring up the nest. What is to become of the young ones when they get out of it, and have never been accustomed to bear themselves up in the invisible ether about them? So 'he fluttereth over his young.' It is a very beautiful word that is employed here, which 'flutter' scarcely gives us. It is the same word that is used in the first chapter of Genesis, about the Spirit of God '_brooding_ on the face of the waters'; and it suggests how near, how all-protecting with expanded wings, the divine Father comes to the child whose restfulness He has disturbed. And is not that true? Had you ever trouble that you took as from Him, which did not bring that hovering presence nearer you, until you could almost feel the motion of the wing, and be brushed by it as it passed protectingly above your head? Ah, yes! 'Stirring the nest' is meant to be the precursor of closer approach of the Father to us; and if we take our changes and our sorrows as loving summonses from Him to effort, be sure that we shall realise Him as near to us, in a fashion that we never did before.
