The more you read these accounts, the more details you notice, and the less you focus on the main plot and instead consider tangential things--like why did God (through Gabriel) make Zachariah mute but not Mary the mother of Jesus?
Now, the more you are actually picturing Jesus walking around and doing that stuff--not only healing people, but rebuking the storm and blowing up the Pharisees on the Law--the more you realize how cool it must have been to be an apostle. You would have been totally relaxed (knowing what you now know) if you were literally walking around following Jesus all day. Even if something terrible did happen to you, with Him standing right next to you and watching you (die of leprosy, get a Roman sword in your gut, etc.), it wouldn't be scary to you right now. You would know that it's unlikely He would really stand there and not comfort you in some way, but also that whatever He did, He would have a really good reason for it. And of course, it would be less than what He did Himself, in pursuit of His grand plan.
I'm sure you see where this is going. If you call yourself a Christian (or at least, a Bible-believing Christian), then you believe that He really is standing next to you all day, and that you ought to be following Him around all day. So you should be just as confident and thrilled with life as you would have been, had you gotten to be James.
