Psalm 90:12 So teach us to number our days, that we may apply our hearts unto wisdom.
Assuming a 75 year life span, a 20 year old has about 20,000 days left, a 30 year old has 16,000, a 40 year old has just under 13,000, a 50 year old has a little more than 9,000, a 60 year old has almost 5,500, and a 70 year old has about 1,800. How many days left do you have in which you can serve the Lord? With days going by faster and faster as we age, no matter how many days we have left, it won’t be long.
James 4:14 Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
Not only should we make a count of the days, but more importantly we should make the days count.
Ephesians 5:15-16 See then that ye walk circumspectly, not as fools, but as wise, 16 Redeeming the time, because the days are evil.
