The Gospel taught by Jesus and the apostles was not fundamentally different from what was understood by Abraham. God, through the Scriptures, "Preached before the gospel unto Abraham" (Gal. 3:8).
Injili aliyoifundisha Yesu na Mitume kwa msingi haikuwa tofauti na alivyoielewa Abrahamu. Mungu, katika maandiko,"Alimhubiri Abrahamu Injili nzima" (Gal. 3:8) Ahadi hizi ni za maana sana hata Petro alizianza na kumaliza kutangaza hadharani habari njema akiwatajia hizo (mdo. 3:13,25).
