There's nothing more inspiring than the power of example. When we see a friend involved in something they feel is important and which clearly lifts them significantly, we'll want to join in if we can. When it's clearly a vital part of their life, there's an added impetus for us to take part.The disciples have been with Jesus as he's taught the crowds, healed the sick and shared food and drink with outcasts. They've seen demons cast out, the religious system (and its leaders) challenged and have committed to following him. Seeing Jesus pray they ask for guidance on how they, too, might keep close to God.
