While regularly prayer and Bible reading is very important to our relationship with God, I think we need to be careful about how much emphasis we put on the time we alot to each on a daily basis.
Let us not forget that owning a Bible and being able to read it daily is something of a luxury afforded to us in the West. And even then, with the daily challenges of work, preparing dinner, and raising a family, getting in a lot of time for either can be challenging for even the best managers of time.
That's not to say it's not possible, and most of us certainly have a lot of time that we regularly waste on mindless and shallow entertainment. But before we come down too hard on others, remember, it was many centuries before Christians even had regular access to a copy of the Scriptures, let alone having their own private copy in their home. And for thousands of years, the average person has worked much longer than a 9-5 job. Many have been forced to work from dawn to dusk, and then still have responsibilities to take care of when they get home.
Praying 2 hours a day, as some like Ravenhill have suggested we do, is something many today cannot afford to find the time to do. Of course, there are people who can. But I remember for several years of my life where I worked 60+ hours a day, and to travel between 2 jobs, and finding significant time to dedicate to both reading my Bible and pray was very difficult. Most of my "quiet time" was spent driving from one job to the next.
