He changes the lives of all those who come to Him by confession and repentance of their sins and surrender to Him by faith. Those who put their trust in Him are not only forgiven, they have eternal life.
Through the power of the Holy Spirit those who follow Jesus become instruments of lasting change in the lives of other individuals, families, communities, cities and nations.
The primary call is to accept Jesus as Saviour; love, worship and serve Him as Lord, and then help and lead others to do the same.
