Fast and active
One traditional approach to prayer is to spend time fasting. This is normally a period without food, in which the time spent not eating is spent in prayer. Fasting is about adopting a less 'cluttered' approach to life, when time to think about where God's call is leading us becomes our focus. Lent is a time when some Christians choose to fast, not always giving up food - but finding special ways to spend more time consciously in God's presence. What about giving up watching television for a week and using the time to pray?
Organise a prayer walk or pilgrimage. Identify points along the way where particular prayers can be said. This could be in an urban or rural setting. Encourage people to talk along the way, but have a silent section - perhaps the last leg of the walk - to allow quiet contemplation and create space to listen to God's prompting as well as talk.
Variations on this theme could include a narrow boat journey, a horse ride, a bike ride, or for those less energetic, a walk around a local park.
