I was talking to a person who struggles with getting depressed in the wintertime when it gets rainy and dark; in fact, I know many people who struggle with that. I go through times when I am flat and unmotivated; I bet most people have those seasons in their lives for various reasons.
I wonder if Jesus did? He never sinned, but going through downtimes isn’t a sin any more than getting a cold is. The Bible says He experienced all that we do, and because of that, He can sympathize with us and come to our aid when we cry out to Him.
Many of the Psalms are a prophecy of the words and emotions of Jesus when He lived His life, and the Psalms are filled with words like “dismayed, bowed down, pining away, my bones are bowed down, my heart is forlorn, and many others.” In almost every event of the Psalmist being down the response was prayer, asking God for strength, joy, peace, and direction. For me, when I am feeling unmotivated and lethargic prayer is almost spontaneous, like the only response that seems reasonable.
Psalms 6:2-9 Be gracious to me, O Lord, for I am pining away; Heal me, O Lord, for my bones are dismayed. And my soul is greatly dismayed; O Lord, rescue my soul; I am weary with my sighing; Every night I make my bed swim, I dissolve my couch with my tears. My eye has wasted away with grief; For the Lord has heard the voice of my weeping. The Lord has heard my supplication, The Lord receives my prayer.
