Who do I pray to?

When I was a young man in DeMolay (a masonic group for boys), we would start every meeting, activity, and meal together with a prayer.  This was much like the practice that we carried on in my home of regular prayer as a family.  Many young men in the group, did not have a tradition of prayer in their homes, were not as familiar with it, and were far from a relationship with our Father in heaven.
When the time came to ask for God's blessing on our activity, sometimes one of those young men had never prayed before.  I loved the first question that would often arise when we talked about prayer.  "Who do I pray to?"
