40 Days of prayer

All great prophets seemed to had their 40 days in the desert. I never really realized it until now, but I had my 40 days when I was in Asia. In that time, I read the Bible, learned a lot about God, but who really has 40 days to give to God, like I did when I was younger? 40 Days with just God, how many people can even think if having that in a life time, I am a pretty lucky individual, I guess that is why God has moved me to share that with people over the next several months.
