A troubled world can produce emotional challenges. There are those "who through fear of death were subject to slavery all their lives" (Heb 2:15). If you are not in control you are subject to depression. The Vet Center has a fifty-eight page cognitive-behavioral workbook to educate vets to improve their coping skills. Cognition is knowing or perceiving the truth of something. However, if your analytical mind allowed you to think illogically in the first place, you'd have to trust that cognitive counseling could modify your thoughts to go back in the right direction. "Watch the path of your feet and all your ways will be established" (Pr 5:26).
Everyone goes through transitions in life which they have to adjust to. The Vet Center has a fifty-four page Purposeful Living Guide to help vets develop their life skills. Some people may be disadvantaged with weaker coping abilities and need to be informed so they can become more resourceful, confident, empowered, and be able to set goals for themselves. With higher stress levels people with low self-esteem tend to have more depression. Cognitive education will mobilize them to ward off becoming hopeless or discouraged. However, there are distinctions of a recuperative nature between those who trust in what the Bible teaches and those who don't rely on God. The latter are "separate from Christ . . . and strangers to the covenants of promise, having no hope and without God in the world" (Eph 2:12).
Additional material available is from other people's experiences. There are extreme situations where people have been physically disabled or have a terminal illness. They ask, "What value and purpose do I have in life?" Consider that "the spirit of a man can endure his sickness, but for a broken spirit who can bear it?" (Pr 18:14). That's when you depend on God. "Those also who suffer according to the will of God shall entrust their souls to a faithful Creator in doing what is right" (1Pe 4:11). Therefore, "cast your burden on the Lord and He will sustain you" (Ps 55:22).
There is a VA workbook "Living with Purpose" cited above. It applies Behavior Modification Therapy (BMT). But Cognitive Behavior Therapy (CBT) isn't mentioned per se in the Bible. However "God created man in His own image" (Ge 1:27), so if therapists successfully use CBT to help people, it is a valid tool for this purpose. There is a text provided by MIRECC to help clinicians utilize the workbook called Cognitive Behavioral Therapy Strategies. These therapies and methods are what professionals use. However, when tailored to an individual situation, other disciplines would be incorporated. On my website the relevant subject matter would be: thinking, depression, and guidance.
