George Mueller discusses the evolution of child care in his time, emphasizing the transition from large institutional homes to smaller family group homes that foster a more natural environment for children. This change, prompted by the 1948 Children Act, aimed to provide emotional and physical development for children from broken homes, with married couples serving as houseparents. Despite the shift in approach, the core principle of relying on God's provision through prayer remained unchanged. The new model focused on nurturing the children's well-being rather than formal education, ensuring that all staff shared a common faith in God. Ultimately, Mueller highlights the importance of adapting to meet the needs of children while maintaining a foundation of faith and prayer.
