Weaned Christians, who use meat rather than milk, “have their senses exercised to discern both good and evil” (Heb. 5:14). Christians have needed the basic principles in every stage of the gospel Church, and the weaning of the Isaac class pertaining to character development has been taking place throughout the Gospel Age. Weaning is a separation (1) from milk to meat and (2) from carnality to spirituality. Spirituality is the opposite of carnality.
