Christ asks no romantic impossibilities from us, but He does ask a continuous, systematic discharge of the duties which depend on our relation to the world, and on our relation to Him. Let it be our life's work to show forth His praise; let the very atmosphere in which we move and have our being be prayer. Let two great currents set ever through our days, which two, like the great movements in the ocean of the air, are but the upper and under halves of the one movement--that beneath with constant energy of desire rushing in from the cold poles to be warmed and expanded at the tropics, where the all-moving sun pours his directest rays; that above charged with rich gifts from the Lord of light, glowing with heat drawn from Him, and made diffusive by His touch, spreading itself out beneficent and life-bringing into all colder lands, swathing the world in soft, warm folds, and turning the polar ice into sweet waters.
In the tabernacle of Israel stood two great emblems of the functions of God's people, which embodied these two sides of the Christian life. Day by day, there ascended from the altar of incense the sweet odour, which symbolised the fragrance of prayer as it wreathes itself upwards to the heavens. Night by night, as darkness fell on the desert and the camp, there shone through the gloom the hospitable light of the great golden candlestick with its seven lamps, whose steady rays outburned the stars that paled with the morning. Side by side they proclaimed to Israel its destiny to be the light of the world, to be a kingdom of priests.
The offices and the honour have passed over to us, and we shall fall beneath our obligations unless we let our light shine constantly before men, and let our voice rise like a fountain night and day' before God--even as He did who, when every man went to his own house, went alone to the Mount of Olives, and in the morning, when every man returned to his daily task, went into the Temple and taught. By His example, by His gifts, by the motive of His love, our resting, working Lord says to each of us, 'Ye that remind God, keep not silence.' Let us answer, 'For Zion's sake will I not hold my peace, and for Jerusalem's sake I will not rest.'
III. Finally, The constant activity of the servants of Christ will secure the constant operation of God's power.
'_Give_ Him no rest': let there be no cessation to Him. These are bold words, which many people would not have been slow to rebuke if they had been anywhere else than in the Bible. Those who remind God are not to suffer Him to be still. The prophet believes that they can regulate the flow of divine energy, can stir up the strength of the Lord.
It is easy to puzzle ourselves with insoluble questions about the co-operation of God's power and man's; but practically, is it not true that God reaches His end, of the establishment of Zion, through the Church? He has not barely willed that the world should be saved, nor barely that it should be saved through Christ, nor barely that it should be saved through the knowledge of Christ; but His will is that the world shall be saved, by faith in the person and work of Christ, proclaimed as a gospel by men who believe it. And, as a matter of fact, is it not true that the energy with which God's power in the gospel manifests itself depends on the zeal and activity and prayerfulness of the Church? The great reservoir is always full--full to the brim; however much may be drawn from it, the water sinks not a hairsbreadth; but the bore of the pipe and the power of the pumping-engine determine the rate at which the stream flows from it. 'He could there do no mighty works because of their unbelief.' The obstruction of indifference dammed back the water of life. The city perishes for thirst if the long line of aqueduct that strides across the plain towards the home of the mountain torrents be ruinous, broken down, choked with rubbish.
