You get the feeling from the Bible that being unsettled is almost a normal part of the process. Not that we should go looking for it-- it will find us soon enough-- but struggling in some way seems like something we should expect on our own spiritual journeys. True struggling in faith is a stretching experience, and without it, you don't mature in your faith. You either remain an infant or get cocky. Feeling dis-ease and challenged in faith may be God pushing us out of our own safety zone, where we rest on our own ideas about God and confuse those ideas with the real thing. God may be pushing us to experience him more fully, with us kicking and screaming all the way if need be. Feeling unsettled may be God telling us lovingly, but still in his typical attention-getting manner, it's time to grow.
