The 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.
