Our second text tells us that if God's arm seems to slumber and really does so, it is because Zion sleeps. In itself that immortal energy knows no variableness. 'He fainteth not, neither is weary.' 'The Lord's arm is not shortened that He cannot save.' 'He that keepeth Israel shall neither slumber nor sleep.' But He works through us; and we have the solemn and awful power of checking the might which would flow through us; of restraining and limiting the Holy One of Israel. It avails nothing that the ocean stretches shoreless to the horizon; a jar can hold only a jarful. The receiver's capacity determines the amount received, and the receiver's desire determines his capacity. The law has ever been, 'according to your faith be it unto you.' God gives as much as we will, as much as we can hold, as much as we use, and far more than we deserve. As long as we will bring our vessels the golden oil will flow, and after the last is filled, there yet remains more that we might have had, if we could have held it, and might have held if we would. 'Ye are not straitened in Me, ye are straitened in yourselves.' So, dear brethren, if we have to lament times of torpor and small success, let us be honest with ourselves, and recognise that all the blame lies with us. If God's arm seems to slumber, it is because we are asleep. His power is invariable, and the Gospel which is committed to our trust has lost none of its ancient power, whatsoever men may say. If there be variations, they cannot be traced to the divine element in the Church, which in itself is constant, but altogether to the human, which shifts and fluctuates, as we only too sadly know. The light in the beacon-tower is steady, and the same; but the beam it throws across the waters sometimes fades to a speck, and sometimes flames out clear and far across the heaving waves, according to the position of the glasses and shades around it. The sun pours out heat as profusely and as long at midwinter as on midsummer-day, and all the difference between the frost and darkness and glowing brightness and flowering life, is simply owing to the earth's place in its orbit and the angle at which the unalterable rays fall upon it. The changes are in the terrestrial sphere; the heavenly is fixed for ever the same.
