Prayer for everyone
Prayer is important and we all want to be better at prayer. But many of us have been put off by spiritual gurus who make a transforming prayer life sound as if it's out of reach to most mere mortals.
Part of the problem is that our modern, technological society naturally gravitates toward prayer that "avails much", i.e., productive prayer. We want quantifiable results. The results of intercessory prayer are easily quantifiable: was the prayer answered with the desired result? If not, then change the expectation (the theologically conservative approach) or the method of prayer (the charismatic approach).
Contemplative prayer is "the other kind of prayer". It's not so much about talking to God (or talking at God) but is about putting ourselves in a place to listen to God. There are many tools for contemplative prayer and it's not necessary to become expert at each. What's more important is becoming familiar with various tools and finding out which ones fit you best.
A prayer retreat for your church or leadership team can take a morning, a morning and afternoon, or extend into the evening. It will include teaching on contemplative prayer and introductions to various prayer tools.
