It can, however, give us some limited but valuable knowledge about God's existence and the historical reality of Jesus that can lead us towards faith and show us that it is not unreasonable to believe. But that kind of reasoning is not faith itself. It is a knowledge born in and from the heart. In a mysterious way God warms and attracts the will so we can make a judgment by means of it. We feel that what is being proposed to us from without, that is, the presentation of the Christian mysteries about God and Jesus, is the same reality that is attracting us from within, and our hearts judge it to be good and see that it ought to be embraced.
Theology is the foundation of Christian prayer and contemplation.
Christian mysticism is not contentless. It is about our experience of Jesus and the Trinity, the very things that theology helps us to get some insight into. The best theology should inspire us and strengthen us to become better Christians. It is the thoughtful reflection on the practical consequences of believing in the Christian mysteries.
