This "casting of the self" became Murray's life theme. Sixty years of ministry in the Dutch Reformed Church of South Africa, more than 200 books and tracts on Christian spirituality and ministry, extensive social work, and the founding of educational institutions—all these were outward signs of the inward grace that Murray experienced by continually casting himself on Christ. "May not a single moment of my life be spent outside the light, love, and joy of God's presence," was his prayer. "And not a moment without the entire surrender of myself as a vessel for him to fill full of his Spirit and his love."
