Mechanics of faith

You may wonder why it’s necessary to spend so much time going over every verse and nuance in the text. We’ve been parked on justification and faith… Why continue? Besides the fact that the apostle Paul does? Well, just as it’s possible to drive your car even if you’re not a mechanic, it’s possible to be a christian without understanding these things fully, but when you break down in the middle of the night, in the rainstorm, on the wrong side of town, having a mechanic in the front seat with you probably is going to do a lot to ease your concerns about the situation. And when challenges and trials come in life, knowing these things in detail can be the difference between worship right there in the midst of the storm and a period of back-sliding when you trust promises of sin and expedience rather than God and righteousness.”
