Prof. Johan Malan's Perseverance of the Saints

Prof. Johan Malan believes in perseverance of the saints, that is you need to persevere in your own strength to be holy otherwise you will lose your salvation.  This is part of the Holiness movement.   Prof John Malan is Arminian, the more modern name for this would be a Methodist.

The holiness movement refers to a set of beliefs and practices emerging from 19th-century Methodism, and to a number of evangelical Christian denominations who emphasize those beliefs as a central doctrine. The movement is distinguished by its emphasis on John Wesley's "Christian perfection" teaching—the belief that it is possible to live free of voluntary sin, and particularly by the belief that this may be accomplished instantaneously through a second work of grace.  en.wikipedia.org/wiki/Holiness_movement‎
