There 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.
You pray and make your requests made known unto God, and God will do something.' It is not your prayer that is going to do it, it is not you who is going to do it, but God. 'The peace of God that passeth all understanding'-He, through it all, 'will keep your hearts and minds in Christ Jesus'.
The whole man is involved, the mind, the heart and the will, and a common cause of spiritual depression is the failure to realize that the Christian life is a whole life, a balanced life.
