This document discusses the concept of drinking the water that God gives and it becoming a fountain within us. It explains that the water refers to the Holy Spirit. Drinking the water involves having faith, obeying God's word, and allowing Christ to dwell within us. As our faith and obedience grows, Christ will live in us more fully and the fountain within will grow larger, springing up into eternal life. The document provides Bible verses to support these points and encourages contacting the author via their website or email for any discussion on disciple training.
