Yesterday's Streams in the desert devotional

I read this last night and I found it very encouraging and challenging.
I hope you are equally encouraged.

Still upward be thine onward course:
For this I pray today;
Still upward as the years go by,
And seasons pass away.

Still upward in this coming year,
Thy path is all untried;
Still upward may'st thou journey on,
Close by thy Saviour's side.

Still upward e'en though sorrow come,
And trials crush thine heart;
Still upward may they draw thy soul,
With Christ to walk apart.

Still upward till the day shall break,
And shadows all have flown;
Still upward till in Heaven you wake,
And stand before the throne.

We ought not to rest content in the mists of the valley when the summit of Tabor awaits us. How pure are the dews of the hills, how fresh is the mountain air, how rich the fare of the dwellers aloft, whose windows look into the New Jerusalem! Many saints are content to live like men in coal mines, who see not the sun. Tears mar their faces when they might anoint them with celestial oil. Satisfied I am that many a believer pines in a dungeon when he might walk on the palace roof, and view the goodly land and Lebanon. Rouse thee, O believer, from thy low condition! Cast away thy sloth, thy lethargy, thy coldness, or whatever interferes with thy chaste and pure love to Christ. Make Him the source, the centre, and the circumference of all thy soul's range of delight. Rest no longer satisfied with thy dwarfish attainments. Aspire to a higher, a nobler, a fuller life. Upward to heaven! Nearer to God!
