There is an old proverb to the effect that 'all those who open their mouths, close their eyes!' The purpose of silence and solitude is to be able to see and hear. Control rather than no noise is the key to silence. James saw clearly that the person who could control his tounge is perfect (James 3:1-12). Under the Discipline of silence and solitude we learn when to speak and when to refrain from speaking.
Richard J. FosterBut if we know that the people of God are first a fellowship of sinners, we are freed to hear the unconditional call of God's love and to confess our needs openly before our brothers and sisters. The fear and pride that clings to us like barnacles cling to others also. In acts of mutual confession we release the power that heals. Our humanity is no longer denied, but transformed.
Richard J. FosterThe Spiritual Disciplines are things that we do. We must never lose sight of this fact. It is one thing to talk piously about 'the solitude of the heart,' but if that does not somehow work its way into our experience, then we have missed the point of the Disciplines. We are dealing with actions, not merely states of mind.
Richard J. FosterA farmer is helpless to grow grain; all he can do is provide the right conditions for the growing of grain. He cultivates the ground, he plants the seed, he waters the plants, and then the natural forces of the earth take over and up comes the grain...This is the way it is with the Spiritual Disciplines - they are a way of sowing to the Spirit... By themselves the Spiritual Disciplines can do nothing; they can only get us to the place where something can be done.
