In Titus 2, Paul exhorted the evangelist, “But as for you, speak the things which are proper for sound doctrine.” This answers the question, “Is doctrine important?” Yes!
But it leads to another question. “What kind of doctrine is sound?” The Greek word translated “sound” (hygiain?) signifies wholeness, wellness (and in the realm of doctrine) uncorruptness. As Thayer put it, “Metaphorically, the phrase is used of one whose Christian opinions are free from any admixture of error.”
Put simply, sound doctrine is teaching that is based solely on God’s word. This is as it has always been, as men have sought to ensure their standing with God. Jesus Himself said, “If you love Me, keep My commandments” (John 14:15).
The scriptures are where we gain access to God’s will. Paul wrote that scripture is inspired of God, and is sufficient for man. It is “profitable for doctrine” and in it alone the “man of God may be complete, thoroughly equipped for every good work” (2 Timothy 3:16-17).
As the Psalmist so wonderfully exclaimed, “How can a young man cleanse his way? By taking heed according to Your word. With my whole heart I have sought You; Oh, let me not wander from Your commandments! Your word I have hidden in my heart, that I might not sin against You” (Psalms 119:9-11).
