In this age of relentless activity it is easy for Christians, particularly those involved in good works, to fall into the pattern of the activist.  But mere activity and material results are not sufficient for a successful apostolate.
In his classic work
The Soul of the Apostolate,
Dom Chautard demonstrates that the very foundation of all apostolic work must be the Interior Life.  The apostle of Christ will grow to become an instrument and true channel of God’s graces to the world only through prayer, meditation and the cultivation of the Interior Life.  When one is involved in works of spiritual or corporal charity, his work can only be truly efficacious when he anchors his Interior Life in Christ.  Without Christ we can do nothing.  Inside you’ll learn about the:
Pre-eminence of the Interior Life over the Active Life
Dangers of the Active Life: for you and your apostolate
The Devil’s  special temptations for those working for Our Lord
Steps necessary in order to develop and grow in the Interior Life
Necessity of the Interior Life to a successful and spiritually fruitful apostolate
For anyone who would work for Our  Lord and His Church there is simply no book more important to read and to follow than
The Soul of the Apostolate
