Fits of depression come over the most of us. Usually cheerful as we may be, we must at intervals be cast down. The strong are not always vigorous, the wise not always ready, the brave not always courageous, and the joyous not always happy.
No sin is necessarily connected with sorrow of heart, for Jesus Christ our Lord once said, "My soul is exceedingly sorrowful, even to death." There was no sin in Him, and consequently none in His deep depression.
