Here is a blog post by Jonathan Parnell who works with the Desiring God organization. I read it with much interest because 3 years ago I started dedicating the 2 hours I spend on the road getting to and from work to time in prayer, study, and meditation upon God. Technology makes it so easy to download a podcast from one of many good expositors of the Word and listen during your commute. You can download many different versions of the Word of God, ESV is my favorite, and listen to almost all of the New Testament Epistles at one time which is the way they were read to the church’s they were intended for. I have not had visions of rapture during every trip, but quite often it is a glorious time of learning something new about my Lord.
If you have a commute, and hopefully it isn’t as long as mine, I highly recommend that you spend your time in this endeavor rather than wasting it listening to talk radio, classic rock, or country music. All of those will pass away but the Word of God will last forever. You will grow in the grace and knowledge of God and find that it was time well spent.
