The Word of God is 'the true light that enlightens everyone who comes into the world' and is the driving force behind the charism of the Immaculate Heart Sisters (IHM). Charles Heerey wanted the Sisters to be 'the fairest of the children of God'. Their life must be modelled on Jesus Christ, the great teacher and master to humanity. In view of this mandate given to them by their founder, this paper sets out to discuss the education mission of the IHM Sisters in Nigeria, their contributions to the mission of educating the people of God in the Church, their prospects and challenges. Hence, the Sisters strive to bring about holistic and total transformation to every child.
