When problems come, we need to take the worry, give it a good whack and send it off. When the volleyball comes our way, if we grab it and hold on to it our team loses the point. In the same way, if we hold on to our worries and meditate on them, we lose the point of it all and head toward defeat.
Rather, when we see that worry come back at us full speed, we must raise our hands and with all our strength send it flying.
And which of you by being anxious can add a single hour to his span of life? (Matthew 6:27 ESV)
