What takes up your time? Where does your mind go when you have down time? What do you spend time pondering? What do you focus on?
I believe we need to guard what we put into our heads because it determines what we focus on when we have down time. If I spend all day focusing on things that bring me down or put negative images into my head, then when I have a moment or two to myself, those are the things that my mind goes to.
As we go through the day we should choose to focus on the things that are honoring to God. Mediate on a scripture throughout the day. Pray continuously. Listen to a sermon or some worship music. Find a way to focus on God and the good things that he does for us.
The apostle Paul wrote to the church in Philippi:
Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
(Phil. 4:8) Paul says that if we think or focus on these things then we will have the peace of God. My prayer for each of us is that we focus on the good things in life and the loving God we serve. My prayer is that we all have the peace of God.
