This gets difficult but its part of our walk with Jesus. The easiest thing to do is just worry until a problem finally passes, but the hard part is to expect the miracles of the Bible to be yours and fix it. Believing is trusting. Sometimes trusting is so hard when all we see is the problem and all we think about is it too. In the same way Casting Our Worries On The Lord is the same process. Make all you see about you problem be the promise of God to get you out of your problem and make every thought you have think how wonderful its going to be to have Jesus get you out of this mess. Thats called "casting your cares over on Him". This takes effort because when things appear hopeless we want to just quit. Don't quit though! Keep up the pressure! Your miracle will happen!
