prayer request

Last night we had an outreach games night which was fun. After, we were talking with one of the guests (Dave, from Ohio) and he mentioned at one point how he wants to go into the army (specifically the air force) and fight for God...Now, earlier in the day I was in a discussion with Michael, one of the cleaners, from England, and we were talking about the story of Gideon and how God picked the "loser" and how God loves to use little people. We also talked about how God could show His power through winning the battle. But Michael really struggles with the fact that God used oppressors and war as a way of punishment, and why didn't He choose another way? So when Dave started talking about joining the army to serve God, Michael left the room shutting the door rather loudly. So please pray for him, and pray for me because I don't know how to answer some of his questions...Thanks!
