The youth of Maranatha Revival Ministries commemorated June 16 by marching in the streets of Vaal and Orange farm - preaching, praying and performing for the community.  
 
June 16 is entitled 'Youth Day', an annual commemoration of the Soweto Uprising, 1976, in which an estimated 176 (some estimate many more) young people lost their lives campaigning in response to the introduction of Afrikaans as the medium of instruction in local schools.  It is a bank holiday across South Africa.
