If we have committed our lives to God, we have done so because we are persuaded that he is real and good. But daily acting on that trust means repeatedly reminding ourselves of his character, in specific and concrete ways. After all, we have an enemy bent on spurring distrust.
So if you watched The Virgin Diaries this weekend, go read Song of Solomon or Genesis 2 or Exodus or Isaiah or the Gospels. Or ask a friend to tell you about a time God showed up and took care of him or her. Retell some of your own stories. You may even want to revisit physical artifacts of such encounters with his faithfulness, be they a car or a purse, a scar or a book or even a street.
There are too many sneering caricatures of our God out there for us to just passively trust him. Loving God with our whole heart, might, and soul takes deliberate, repeated retelling and richly embodied practices.
