Here’s Lloyd Jones. Listen up!
“…The great antidote to spiritual depression is the knowledge of Bible doctrine, Christian doctrine. Not having the feelings worked up in meetings, but knowing the principles of the faith, knowing and understanding the doctrines. That is the Biblical way, that is Christ’s own way as it is also the way of the apostles. The antidote to spiritual depression is to have a knowledge of Him, and you get that in His Word. You must take the trouble to learn it. It is difficult work, but you have to study it and give yourself to it.”
“The Christian faith begins and ends with a knowledge of the Lord. It begins with a knowledge of the Lord – not a feeling, not an act of will, but a knowledge of this Blessed Person.”
D. M. Martin Lloyd-Jones, Spiritual Depression: Its Causes and Cures, chapter 11.
