St Teresa gives several examples from the world of business to help her friends see what failing to resign oneself to God's will looks like. She wants us to pray for the grace of healing, healing for our wounded souls. So often we want things just according to our taste. We so often fail to surrender to God's plans. We can even get discouraged at the lack of progress we have made. In all these matters, she wants us to practice humility, surrendering ourselves to God.
