Our mission is to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men in the cunning craftiness of deceitful plotting.    (Ephesians 4:12-14)

And this is done by teaching the whole counsel of God. That is why we teach the Bible book by book, chapter by chapter and verse by verse
