From: Starting Your Day Right daily devotionals by:Joyce Meyer

Look carefully then how you walk! Live purposefully and worthily and accurately, not as the unwise and witless, but as wise (sensible, intelligent people), making the very most of the time [buying up each opportunity].
Ephesians 5:15-16

We need to be so self-controlled that we don't waste time. That doesn't mean that we can never do anything fun. It doesn't mean we can't do things that we enjoy.
We don't need to be rigid, stiff, or boring. But we do need to use our time wisely, choosing to give the best part of our day to spend time with God.
The Word encourages us to be prepared, saying, "Hear counsel, receive instruction, and accept correction, that you may be wise in the time to come" (Proverbs 19:20). Starting your day with God's instruction will keep you walking in wisdom, making the most of your time.
