Priorities determine the course of our lives, and daily choices determine priorities.
Our first priority should be God (Matthew 6:33), but that doesn't mean we spend all day at church. It means we let God govern our time. We want to be flexible and open to "divine interruptions" but we still need a "plan."
"Teach us to number our days, that we may gain a heart of wisdom." Psalm 90:12
Without a budget, we often spend money impulsively or carelessly. Without a "time budget," we usually spend our time impulsively or carelessly.
It isn't always the bad choices that trip us up. Often it's spending too much time on one good thing while neglecting another.
If you faithfully spend time with God each day, statistics show you're in the minority of believers.(1) And this is our greatest priority problem.
Why not take some time to make a "time budget" that includes time for God and allows you to do all of those things He's prepared in advance for your schedule (Ephesians 2:10)!
