Just because 8 ounces of steak is good for our bodies, it doesn't mean we can take in 80 ounces in one day. And just because one sermon is good, it doesn't mean we can take in 10 sermons a week. While personal daily devotions is a means for daily nourishment, it doesn't mean God has designed us to take in 8 hours of bible reading each day. He has designed us to work and create, to labor and contribute, to serve and to give-- to live out what we have been given in Christ.
