According to a Reuters article, nearly 1 in 5 Americans suffered from 'mental illness' in 2009. That accounts for 11 million adults. By this, it seems that depression is what is considered 'mental illness' and is highest among 18 to 25 year old's presumably because of rising unemployment.
God's Word tells us:
Matthew 6:25-34 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment? Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they? Which of you by taking thought can add one cubit unto his stature? And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith? Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed? (For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things. But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
The cure for a troubled heart is to trust Jesus and pray.
Philippians 4:6-7 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
The article by Reuters suggests that not enough people are getting the help they need. Our country is hurting right now and the answers are to be found in the Word of God. Let's pray for those without a job and let's share the gospel with them. They need Jesus, he is the Provider!
