Basing theology on the lived experience of God has another important benefit: by including the experience of the whole person, rather than just their intellect, it allows for a theology that is as much of the heart as of the mind.
Theology is not compartmentalised, kept separate from the rest of the spiritual life, but becomes part of our everyday reflection on our relationship with God. In this way, it becomes the task of the whole people of God rather than only those with higher degrees. It also becomes the task of the whole person rather than the intellect alone.
This sort of theology is not locked away in esoteric textbooks but is to be found in every church that takes its Christian living seriously.
