There’s something I’ve noticed about my own life: if I don’t intentionally leave room for something, something else will fill the space. It happens with my calendar. It happens with my money. It happens with my energy. And I wonder if one of the quiet spiritual dangers of modern life is that we can fill our lives so completely with good things that we leave very little room for the things of God.

I don’t think most Christians intentionally decide that church isn’t important, that they don’t want to serve, or that they don’t want to give generously. In fact, I think most sincere Christians really do want those things to be part of their livesThe problem is that sometimes there’s nothing left. Every night of the week is already committed, so gathering with the church becomes difficult. Every dollar is already assigned to payments, subscriptions, activities, vacations, hobbies, and the lifestyle we’ve chosen, so generosity feels impossible. Every ounce of energy is spent on work, family, sports, projects, and recreation, so serving feels like one more thing we simply cannot handle. None of those individual choices necessarily represents a rejection of God. But taken together, they can create a life with very little room for His kingdom.

Jesus said, “But seek first the kingdom of God and his righteousness” (Matthew 6:33). That word first matters. Kingdom priorities cannot consistently receive whatever happens to be left over. At some point, following Jesus requires us to arrange the other parts of our lives around what matters most.

That may mean protecting some space on the calendar rather than filling every available evening. It may mean deciding to give before deciding how much lifestyle we can afford. It may mean saying no to something good because we want enough energy to say yes when there is an opportunity to serve. It may even mean intentionally living with a little less—less scheduled, less spent, less committed—so that we remain available to God.

That’s what margin does. Margin gives you room to say yes. When someone needs help, you have room to help. When there is an opportunity to serve, you have room to serve. When the church gathers, your calendar isn’t perpetually competing against it. When God gives you an opportunity to be generous, every dollar hasn’t already been promised somewhere else.

And this isn’t a call to attend every event, give away every dollar, or exhaust yourself serving. We have limits, and wisdom recognizes them. The question is whether our limits are being reached by kingdom priorities—or whether everything else is reaching them first.

Take an honest look at your calendar, your budget, and your energy. Have you left any room for the kingdom? Because if we don’t intentionally make room for what matters most, something less important will gladly take its place.
