We are consumed by your anger and terrified by your indignation. You have set our iniquities before you, our secret sins in the light of your presence. All our days pass away under your wrath; we finish our years with a moan. Our days may come to seventy years, or eighty, if our strength endures; yet the best of them are but trouble and sorrow, for they quickly pass, and we fly away. If only we knew the power of your anger! Your wrath is as great as the fear that is your due. Teach us to number our days, that we may gain a heart of wisdom. Psalm 90:7-12

The sobering reality of a limited lifespan brings an excellent clarity of thought. Whether you think about this or not, there is a one hundred percent chance you will die someday. Without getting too morbid, just consider the fact that our days are numbered. Every time I've experienced how fragile and short life is, that moment produces in me a sharpening that is hard to describe. After death I know I will stand before God and give account. I also understand I will leave a legacy behind. Why are men wise to number their days? 

A heart of wisdom comes from thinking about our limits. The psalmist goes on to ask God to "Satisfy us in the morning with your unfailing love, that we may sing for joy and be glad all our days." He understands God's hand in all of life and defers to God. Develop and train yourself with the humility that comes from considering the limits of a man's life. A heart of wisdom is out there to be gained, pick it up by numbering your days. 

DO THIS TODAY: Start thinking about your limits and praise the Unlimited God.
