He returned to Norway in December 1906 without funds or church support. Nevertheless, starting in 1907, he held revival meetings in Oslo which attracted international attention, and he became one of the prime movers of the Pentecostal movement in Europe.

They became leaders of the Pentecostal movement in their respective countries.
