19. The second part deals with the resurrection of Christ and its power through faith. This is the goal Paul has in view when he tells them that they have slain the Christ, thus effecting their condemnation by God and forfeiting whatever glory they possessed as Jews, gaining shame and wrath before God in its stead. To be still delivered from such condemnation, and to obtain justification and salvation, as he expresses himself toward the end, it is necessary to hear and believe the word concerning the selfsame Christ. Moreover, inasmuch as they with their leaders have refused to receive and recognize this Messiah when he preached and wrought miracles in person; now, that he is invisible and absent in the body, they are called upon to receive him whom they themselves have crucified unto death, and to believe that he is risen from the dead as Lord over all, according to the testimony of the apostles.
The dreams of the past they are now utterly to forsake, and their expectations of a Messiah still to come and elevate them with their Law and manner of worship to fame, riches and position, and to spread abroad their Moses and their priesthood in all the earth. They must now thank God for being placed on the same footing with the gentiles, in that they may come with them to the Word of salvation for the purpose of obtaining God's favor, remission of sins and life eternal.
