"Then the apostle set before them the great truths that are the foundation of the Christian's hope. He told them of Christ's life on this earth and of His cruel death of shame. He told them how the Lord of life had broken the barriers of the tomb and risen triumphant over death. He repeated the Saviour's commission to His disciples: “All power is given unto Me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” Matthew 28:18, 19 . He told them also of Christ's promise to send the Comforter, through whose power mighty signs and wonders would be wrought, and he described how gloriously this promise had been fulfilled on the Day of Pentecost. AA 282.3"
