Repentance is a characteristic of the whole life, not the action of a single moment.
 Sinclair B. Ferguson
It is only when we want to take our lives out of the Father’s hands and have them under our own control that we find ourselves gripped with anxiety. The secret of freedom from anxiety is freedom from ourselves and abandonment of our own plans. But that spirit emerges in our lives only when our minds are filled with the knowledge that our Father can be trusted implicitly to supply everything we need.

Remember that you are not saved by increased levels of holiness, however desirable it is that you should reach them. ...It is Christ who saves us-through faith.
