One of my favorite scriptures is Ephesians 5:16, where it speaks of redeeming the time. We often speak of making the most of every opportunity, time being short, etc. However, I read an interesting commentary that brought in the fact that to redeem is to gain or regain possession of something. We regain our time to be used for good things rather than bad. God redeems us so we can be restored and used for good.
I'll still miss that hour of sleep....but maybe now I won't waste time grumbling about it!
