But is there any necessity for such alternations? Some degree of fluctuation there will always be. The very exercise of emotion tends to its extinction. Varying conditions of health and other externals will affect the buoyancy and clear-sightedness and vivacity of the spiritual life. Only a barometer that is out of order will always stand at set fair. The vane which never points but to south is rusty and means nothing. But while there cannot be absolute uniformity, there might and should be a far nearer approach to an equable temperature of a much higher range than the readings of most professing Christians give. There is, indeed, a dismally uniform arctic temperature in many of them. Their hearts are fixed, truly, but fixed on earth. Their frost is broken by no thaw, their tepid formalism interrupted by no disturbing enthusiasm. We do not now speak of these, but of those who have moments of illumination, of communion, of submission of will, which fade all too soon. To such we would earnestly say that these moments may be prolonged and made more continuous. We need not be at the mercy of our own unregulated feelings. We can control our hearts, and keep them fixed, even if they should wish to wander. If we would possess the blessing of an approximately uniform religious life, we must assert the control of ourselves and use both bridle and spur. A great many religious people seem to think that 'good times' come and go, and that they can do nothing to bring or keep or banish them. But that is not so. If the fire is burning low, there is such a thing on the hearth as a poker, and coals are at hand. If we feel our faith falling asleep, are we powerless to rouse it? Cannot we say 'I _will_ trust'? Let us learn that the variations in our religious emotions are largely subject to our own control, and may, if we will govern ourselves, be brought far nearer to uniformity than they ordinarily are.
