Walter is the founder of HELP for all Nations, president of the Free Christian Youth Community (FCJG) in Lüdenscheid (Germany) and HELP International, the international branch of FCJG overseeing and covering the international ministries in Europe, Asia and the USA. He had a powerful encounter with God while he was still a drug addict with no Christian around, and God radically turned Walter's life. Since this encounter Walter has been walking with God. Walter's heart is fervently burning for Jesus, revival and missions.
He is a nationally and internationally credited and well-known evangelist and conference speaker, who spends several months per year abroad ministering to churches, running crusades and ministering to the poor, needy and the lost.
