The document discusses why studying Bible doctrine is important. It argues that doctrinal study (1) gives an orderly understanding of biblical truths, (2) grounds our faith firmly in God's word, and (3) was important to Jesus, the disciples, Paul, and the early church. Right teaching leads to spiritual growth, maturity, freedom from deception, obedience to God's commands, and the ability to teach others. Studying doctrine helps protect against false teachings and brings spiritual riches.
