Ephesians 5:15-17

Be very careful, then, how you live – not as unwise but as wise, making the most of every opportunity, because the days are evil. Therefore do not be foolish, but understand what the Lord’s will is.

Make the most of the time. This is specific time not just a matter of chronology. Kairos not chronos. A precise moment waiting to be clutched, seized, laid hold of, made use of. Jesus tells us that the time has come. Mark 1.15. And what are we to do with this time, this now, this very moment of opportunity? We are to redeem it. And redeem it doubly. Once because our use of time is meant to compensate for the ways in which the world fails to use time well: as our saviour compensated for our failure on the cross so we make up for the world's wasted time. And twice because the second aspect of redemption is about payment. To redeem is to regain something in exchange for something else. In other words, redeeming our time is going to cost us something. What is the cost then? Jesus loves to turn our perception of cost effective time use on its head. Be wise but don't succumb to worldly wisdom. Godly use of time is probably going to look stupid because god has made foolish the wisdom of the wise. 1 Corinthians 1.20. God's folly is wiser than man's wisdom and he will use such folly to shame those who think they are wise. 1 Corinthians 1.27. God's wisdom is precisely not the wisdom of this age - 1 Corinthians 2.6 - so to walk in it we will look pretty silly. And so, be wise today. Be foolish.
