Imagine accusing the Lord of not caring. He lovingly but honestly answered her. “Martha, Martha, you are worried and troubled about many things. But one thing is needed, and Mary has chosen that good part, which will not be taken away from her.” (Luke 10:38-42) Jesus told her that she was worried, or anxious and distracted in her mind as well as troubled. The Greek word troubled is the basis of the English word turbulent. In this usage, it means that Martha's mind was in confusion, cluttered and crammed full with cares. Jesus wasn't condemning her, but pointing out that Mary had made the better choice, which was to sit at the feet of the Master and listen to His Word.
To learn to trust God in hard times requires time in God's Word, reading the Bible. Times are hard because the world is filled with problems and there are innumerable distractions, all stirred up and manipulated by the adversary. Satan's goal is to cause fear and worry in people, to divert Christians away from God.
When Christians don't read the Bible and meditate on the words of the Master, they are easily distracted and start to worry about all the insane and evil things going on all around the world. But God's Word instructs believers what to do to trust God in hard times. “Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God.” (Philippians 4:6) The answers to cares are prayers. The antidote for worry is to specifically pray about everything, and with thankfulness, make known to God every request.
It is certain that worry accomplishes nothing, but prayer appeals to God. God's Word says that He hears the prayer of the righteous and that the prayer of the upright is His delight. (Proverbs 15:8,29) Corrie ten Boom, the Christian Holocaust survivor who helped many Jews escape the Nazis during World War II, said, “Any concern too small to be turned into a prayer is too small to be made into a burden.” Wise advice indeed. Be anxious for nothing, but pray for everything, and be thankful. Don't worry, be happy.
Scottish author, poet and Christian minister, George MacDonald said, “It is not the cares of today, but the cares of tomorrow, that weigh a man down. No man ever sank under the burden of the day. It is when tomorrow's burden is added to the burden of today that the weight is more than a man can bear.”
Peter's first epistle has this comforting advice: “casting all your care upon Him, for He cares for you.” (1 Peter 5:7) Worrying about things beyond ones control is a total waste of time and energy. Again, Jesus brings to the forefront the believer's priority. “And do not seek what you should eat or what you should drink, nor have an anxious mind. For all these things the nations of the world seek after, and your Father knows that you need these things. But seek the kingdom of God, and all these things shall be added to you.” (Luke 12:29-31)
