Johannesburg is a thriving global city; it is in one of the wealthiest regions in Africa but also one of the most violent.

It is a city of extremes but, according to Nat and Helen, a great place to live and minister. Nat and Helen were invited to set up the Johannesburg Bible College (JBC) in 2005. JBC equips and inspires men and women for bible teaching ministries and also operates in Soweto, various other townships, and university campuses. There are growing opportunities to facilitate similar courses across southern Africa.

Nat and Helen have four children: Miriam, Christopher, Bethany and Isaac.
