And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed. – Romans 13:11

Brethren, slumber impoverishes us. The sluggard, and the thistle and thorn, always go together, and rags and poverty follow close behind. You may miss, by your sleep, great spiritual profit. You cannot expect sleepy Christians to grow in grace. They will miss many instructive things in God’s Word, many precious promises meant only for the wakeful. They will lose high enjoyments and spiritual banquetings, for the king’s entertainments are not for those who fold their arms and toss upon the bed of indolence. Wealth lies in the field of the wakeful, but the lover of ease shall have want come upon him as an armed man. I blow the trumpet in Zion, and sound an alarm in God’s holy mountain, for it is high time to awake out of sleep.

Awaken too, my brother, for you are losing opportunities for usefulness. While you sleep men are dying. See how the cemeteries are becoming crowded, how the area of them has to be enlarged. Day by day you see wending through the streets the funeral procession: men, gone beyond the reach of your instructions and your warnings, are carried to their long homes. Awake then, awake, for death is busy everywhere…Awake, for perhaps while you are asleep another heart that is now accessible to the gospel may become finally hardened. Conscience will soon become seared, and then there is nothing for zeal and earnestness to work upon. It will be too late for you to put the seal upon the wax when once it is cool. Quick, sir; while the wax is soft put the seal down! How many opportunities for good we all miss! But those who are asleep lose all their opportunities, and they will be surely required of them when the Master comes. ~ C.H. Spurgeon
