Most of us have heard about the Holy Spirit and most of us have learned about the Holy Spirit, but many times that is as far as our experience has gone. The Holy Spirit is a real person, a part of the Blessed Trinity just like Jesus and the Father. We receive the Holy Spirit through the Sacraments of Baptism and Confirmation. Through what is called the baptism in the Holy Spirit, a personal conversion experience, the power that is the Holy Spirit is released within us.

There is a difference between a seven week LIS seminar and one that is on one day.
