If we give a neighbor a key to our front door, it’s because we trust they understand how to be responsible with that kind of access. And if there is an indication that our neighbor isn’t being responsible with the access we’ve given them, we know restricting that access is wise. I haven’t been as wise about understanding how to guard my heart. Maybe this has been a problem for many of us. Proverbs 4:23 says, “Above all else, guard your heart, for everything you do flows from it.”
