This has always been clear and perhaps well understood about children. But, not until recently has it become equally clear that adults also change as they age.
Adults have a variety of life experiences, and no two lives are the same.
Adults have different cultural and socio-economic backgrounds, educational attainments, vocational opportunities, friends and relationships, and health conditions. And, although we most often think of the physical and psychological changes that occur throughout adulthood, change can and does occur in spiritual development. Adult faith formation, by which people consciously grow in the life of Christ through worship, prayer, study, and service, is a central task of the church. To grow in discipleship throughout life, adults need a deepening relationship with God and community, solid resources, and a positive environment that will help undergird their faith development for the transformation of the world in the 21 st century. In order to help adults grow in Christian faith, you need to know something about the adult life cycle and the kinds of needs, interests, and concerns adults experience at various stages of adulthood.
