"I need to" or "I am"?

Here is the train illustration Tim Rule used when he spoke to us a few weeks ago at our Cru Fall Retreat. As you may remember if you were there, the facts we believe and put our faith in lead to the feelings we experience. If your Christian life has consisted more of thoughts about what you need to do, instead of living out of your position in Christ, perhaps this would be worth looking over again. It goes well with a reading of Ephesians 1.
