Matthew 28:18-20 (NKJV) 18 And Jesus came and spoke to them, saying, “All authority has been given to Me in heaven and on earth. 19 Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age.” Amen."

Pastor Harms did an amazing work in (1) bringing a spirituality to his congregation that resulted in a seventeen year period of revival—only one person in the village did not appear to be a serious and devoted Christian; and (2) founding a mission enterprise which in seven years grew to include eight self-sustaining mission stations on multiple continents on 40,000 acres of land, several mission schools, a home for convicts, and a publishing ministry that had a circulation to 14,000 individuals. All of the gains came as a result of prayer. He was unfortunately in much pain almost all of his life, but saw the pain as a blessing since it allowed him to spend more time praying!
