No unwelcome tasks become any the less unwelcome by putting them off till tomorrow. It is only when they are behind us and done, that we begin to find that there is a sweetness to be tasted afterwards, and that the remembrance of unwelcome duties unhesitatingly done is welcome and pleasant. Accomplished, they are full of blessing, and there is a smile on their faces as they leave us. Undone, they stand threatening and disturbing our tranquility, and hindering our communion with God. If there be lying before you any bit of work from which you shrink, go straight up to it, and do it at once. The only way to get rid of it is to do it.

Alexander Maclaren 

Procrastination, the thief of time, is one of the devil’s most potent weapons for defrauding us of eternal heritage. The habit of “putting off” is fatal to spiritual leadership. Its power resides in our natural reluctance to come to grips with important decisions. Making decisions, and acting on them, always requires moral energy. But the passing of time never makes action easier; quite the opposite. Most decisions are more difficult a day later, and you may also lose an advantage by such delay. The nettle will never be easier to grasp than now.

Oswald Sanders – Spiritual Leadership, Moody Publishers, 1967, p. 98.

How soon “not now” becomes “never.”

Martin Luther

Tomorrow is the devil’s day, but today is God’s. Satan does not care how spiritual your intentions are, or how holy your resolutions, if only they are determined to be done tomorrow.

J.C. Ryle – Thoughts for Young Men.

Whatever your hand finds to do, verily, do it with all your might; for there is no activity or planning or knowledge or wisdom in Sheol where you are going.

Ecclesiastes 9:10

And as he (Paul) was discussing righteousness, self-control and the judgment to come, Felix became frightened and said, “Go away for the present, and when I find time, I will summon you.”

Acts 24:25
