Yes, we must pray for him.
To help with your bible study, though, remember that Mike has many old postings saved on the google site. So if you know what the reading is going to be that day, you can go to the webpage I gave above and in the search bar at the top type something like "matthew 6:24-34" and it will not only give you Mike's Saturday post, but also a number of identical posts from previous years. That way you can get the same information, but you need to work a little for it. I've done that before when I've lost email and still wanted the readings.
Perhaps your bulletin has a list of the readings to search for, or you can go to the US bishops' site here. It will give you the readings of the day, but the calendar there will let you select a different day if you like.
