I just read this yesterday…and absolutely love it.

Call Back

If you have gone a little way ahead of me, call back–
'Twill cheer my heart and help my feet along the stony track;
And, if perchance, faith's light is dim, because the oil is low,
Your call will guide my lagging course as wearily I go.

Call back, and tell me that He went with you into the storm;
Call back, and say He kept you when the forest's roots were torn;
That when the heavens thundered and the earthquake shook the hill,
He bore you up and held you when the very air was still.

O friend, call back and tell me, for I cannot see your face;
They say it glows with triumph, and your feet bound in the race;
But there are mists between us, and my spirit eyes are dim,
And I cannot see the glory, though I long for word of Him.

But if you'll say He heard you when your prayer was but a cry,
And if you'll say He saw you through the night's sin-darkened sky,
If you have gone a little way ahead, O friend, call back–
'Twill cheer my heart and help my feet along the stony track.
