The Old Testament records Jehovah God’s work of decreeing laws and commandments and guiding the life of man during the Age of Law; the New Testament records the work of redemption carried out by the Lord Jesus during the Age of Grace; and The Word Appears in the Flesh is all of the truths for the purification and salvation of mankind expressed by Almighty God during the Age of Kingdom, as well as an account of God’s work of judgment during the last days.
Agano la Kale linarekodi kazi ya Yehova Mungu ya kuamuru sheria na amri na kuongoza maisha ya mwanadamu wakati wa Enzi ya Sheria; Agano Jipya linarekodi kazi ya ukombozi iliyofanywa na Bwana Yesu wakati wa Enzi ya Neema; na Neno Laonekana katika Mwili ni ukweli wote kwa ajili ya utakaso na wokovu wa wanadamu ulioonyeshwa na Mwenyezi Mungu wakati wa Enzi ya Ufalme, pamoja na maelezo ya kazi ya hukumu ya Mungu katika siku za mwisho.
