The same knowledge is our refuge from our own consciousness of weakness. We look up, as a climber may do in some Alpine ravine, upon the smooth gleaming walls of the cliff that rises above us. It is marble, it is fair, there are lovely lands on the summit, but nothing that has not wings can get there. We try, but slip backwards almost as much as we rise. What is to be done? Are we to sit down at the foot of the cliff, and say, 'We cannot climb, let us be content with the luscious herbage and sheltered ease below?' Yes! That is what we are tempted to say. But look! a mighty hand reaches over, an arm is stretched down, the hand grasps us, and lifts us, and sets us there. 'No man hath ascended up into heaven save He that came down from heaven,' and having returned thither stoops thence, and will lift us to Himself. I am a poor, weak creature. Yes! I am all full of sin and corruption. Yes! I am ashamed of myself every day. Yes! I am too heavy to climb, and have no wings to fly, and am bound here by chains manifold. Yes! But we know the exceeding greatness of the power, and we triumph in Him. That knowledge should shame us into contrition, when we think of such force at our disposal, and such poor results. That knowledge should widen our conceptions, enlarge our desires, breathe a brave confidence into our hopes, should teach us to expect great things of God, and to be intolerant of present attainments whilst anything remains unattained. And it should stimulate our vigorous effort, for no man will long seek to be better, if he is convinced that the effort is hopeless. Learn to realise the exceeding greatness of the power that will clothe your weakness. 'Lift up your eyes on high, and behold who hath created these things, for that He is strong in might, not one faileth.' That is wonderful, but here is a far nobler operation of the divine power. It is great to 'preserve the ancient heavens' fresh and strong by His might, but it is greater to come down to my weakness, to 'give power to the faint,' and 'increase strength to them that have no might.' And that is what He will do with us. III. Lastly, notice the conditions for the operations of the power. 'To usward who believe,' says Paul. He has been talking to these Ephesians, and saying 'ye,' but now, by that 'us,' he places himself beside them, identifies himself with them, and declares that all his gifts and strength come to him on precisely the same conditions on which theirs do to them; and that he, like them, is a waiter upon that grace which God bestows on them that trust Him. 'To usward who believe.' Once more we are back at the old truth which we can never make too emphatic and plain, that the one condition of the weakest among us being strong with the strength of the Lord is simple trust in Him, verified, of course, by continuance and by effort.
