Spiritual depression or unhappiness in the Christian life is very often due to our failure to realize the greatness of the gospel.
Martyn Lloyd-JonesThere are ideas in our hearts, there are wishes, there are aspirations, there are groanings, there are sighings that the world knows nothing about; but God knows them. So words are not always necessary. When we cannot express our feelings except in wordless groanings, God knows exactly what is happening.
