The ultimate cause of spiritual depression is unbelief. For if it were not for unbelief, even the devil could do nothing. It is because we listen to the devil instead of listening to God that we go down before him and fall before his attacks.
Martyn Lloyd-JonesSpiritual depression or unhappiness in the Christian life is very often due to our failure to realize the greatness of the gospel.
Martyn Lloyd-JonesWe must re-grasp the idea of church membership as being the membership of the body of Christ and as the biggest honour which can come man's way in this world.
Martyn Lloyd-JonesA Christian is something before he does anything; and we have to be Christian before we can act as Christians.
Martyn Lloyd-JonesThe Christian is not superficial in any sense, but is fundamentally serious and fundamentally happy. You see, the joy of the Christian is a holy joy; the happiness of the Christian is a serious happiness. ... it is a solemn joy, it is a holy joy, it is a serious happiness; so that, though he is grave and sober-minded and serious, he is never cold and prohibitive.
