Throughout history Christians have seen certain people or types of people as having gifts of teaching or encouragement or prayer. Monks and nuns were definitely in this category but they are less numerous now than in the Middle Ages.
Supporting each other and being supported in our faith journeys is important. Local churches should be places of such support, but you may also want to find an individual who can help you grow in their faith. In most cases, the first person to talk to is your minister, if you think you would like to explore having or being a spiritual companion or prayer partner. There is training available at different levels but it is best done with full support of your minister and the local church.
Spiritual direction can appear or feel very different depending on the church tradition, whether more charismatic, evangelical, catholic, etc. The wisdom and insights of different denominations and traditions are also shared generously. It is worth looking and trying to find a model and practice which 'works' for you; some people choose an approach which is very similar to their own tradition, while others recognise that someone from a different tradition may have real insights for them.
