"The strong are not always vigourous,
the wise not always ready.
The brave not always courageous,
and the joyous not always happy.
Charles H. Spurgeon (1834-1892)
Charles H. Spurgeon fought depression and severe anxiety throughout his lifetime. Yet he kept on preaching throughout his illnesses and put out a prodigious 3500 sermons and 135 books. And he said he hated writing!
Out of depression can come blessing, even though while in it not much but agony can be perceived. God sends suffering in order to teach, like it says in Romans 5:3-5 "knowing that suffering produces endurance, 4 and endurance produces character,
and character produces hope, 5 and hope does not put us to shame"
Waiting on God in the midst of darkness takes extreme effort yet the soul does wait for Him more than watchmen wait for the morning (referencing Psalm 130).
God's mercy and grace are new every morning. His word is my lamp and the light to my feet. His praise is continually in my mouth and I thank Him for His leading.
Psalm 103:1-4
Bless the Lord, O my soul,
and all that is within me,
bless his holy name!
Bless the Lord, O my soul,
and forget not all his benefits,
who forgives all your iniquity,
who heals all your diseases,
who redeems your life from the pit,
who crowns you with steadfast love and mercy,
