Christian growth is a multi-dimensional endeavour which addresses the whole person. This talk focuses on the spiritual life or the spiritual disciplines as a key to spiritual growth. As a foundation for growth as a disciple, Jesus emphasised that a person must be born again by the Spirit of God (Jn 3:1-15). In other words, growth is dependent upon internal regeneration through the Spirit. This stands in contrast to the teachings of the Pharisees, who focused on external appearances (Matt 23:25-28). Jesus emphasised that the heart is the source of what we are on the outside (Matt 12:33-37). Hence, change needs to occur from the inside-out. This talk addresses key themes, including self-denial, cross-bearing, and costly life-long discipleship.
