Depression is a state of unhappiness and hopelessness - a psychiatric disorder manifested by persistent feelings of dejection, lack of energy, poor concentration and sometimes suicidal thoughts. There are many causes of depression such as trauma or even sin. I am not a medical doctor so, I will approach this issue from a biblical perspective and give ways of dealing with it regardless of the cause.
Depression can afflict anybody. Great leaders such as Winston Churchill, Abraham Lincoln and Charles Spurgeon suffered from depression. One psychologist termed it as 'the common cold of emotional health'. Several men of God in the Bible - including Moses, King David, and Elijah - battled depression.
