Yet you do not know what your life will be like tomorrow. You are just a vapour that appears for a little while and then vanishes away. James 4:14

The old expressions, “when I get around to it” or “one of these days is what underlines much of our extra activity in life. But so often our motivation to pursue these ‘extra curriculum’ projects to their completion is destroyed because we choose to procrastinate. That is, we just let things slide in thier priority scale and often they are never achieved. And the further we let them slide the less our motivation to begin them. I am guilty of this often when it comes to projects around the house, in the garden, fixing something that needs attention. We all procrastinate in some form or other. 

Someone rightly said - “procrastination is the assassination of motivation.”

The same principal can be applied to our spiritual wellbeing. It's our responsibility to “discipline ourselves for purpose of godliness” (1Tim. 4:7). All the good intentions and desires, if put into the “get around to it,” “one of these days” box, is spiritual procrastination. 

That is dangerous, for your spiritual welfare and worse, a rejection of God’s purpose for His gospel in your life.  Now is the day, “…today if you hear his voice, do not harden your hearts.” (Heb 4.7) 

J.C Ryle once wrote “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. (Grace Quotes)
