A major service of spirituial disciplines – such as solitude (being alone with God for long periods of time), fasting (learning freedom from food and how God directly nourishes us), worship (adoration of God) and service (doing good for others with no thought for ourselves) is to cause the duplicity and malice that is buried in our will and character to surface and be dealt with.
