Here, Jesus isn’t talking about being concerned where you’re going on Summer vacation, or fretting over which new car to buy. When He tells us not to worry about our life, Jesus means the bare bones basics of food, shelter, & clothing. And He goes on in Matthew 6 to make it very clear that our worrying changes nothing…”Who of you by worrying can add a single hour to his life? (or as other translations read, ” Can add a single cubit to his height?”) But the worrying kicker is found in verse 30 when Jesus calls it for what it is…”Oh you of little faith.” Worry is nothing more than unbelief, doubt, and lack of trust that God can look after the very practical details of our life. And it reveals our faltering faith in our Heavenly Father’s ability to care for us in the area of basic resources that He already knows we need. Worrying is unproductive & futile and does not change anything…only heightening our anxiety level.
