Jeus Christ said, “My kingdom is not of this world”. That’s the gospel; the hope of life everlasting. And he would be the key that opens the door, just as he told Nicodemas: “For God sent not his Son into the world to condemn the world; but that the world through him might be saved.” John 3:17
But he had to shed his blood to tear down the wall of sin that separated God from mankind. The testament was of no effect while the testator lived. It required the death of the testator, Jesus Christ.
Jesus Christ told Peter, in Luke 22:32, that “When thou art converted strengthen the brethern”. He told them to tarry in Jerusalem for the promise of the Father.
**Paul specifically states that the gospel of the grace of God is the preaching of the cross (1 Cor. 1:18), that Christ died FOR OUR SINS, was buried and rose again. That is the gospel of the grace of God.**
So, you don’t think that that was same message Peter preached to Cornelius and his household? His message began this way: “Of a truth I perceive that God is not respecter of persons: But in EVERY nation he that feareth him, and WORKETH righteousness, is accepted with him”.(Acts 10:34,35).
Just as he did to the Jews (in Acts 2:14-36), He preached to Cornelius, Christ and him crucified, the resurrection, and remission of sins to those that believe. Acts 10:36-43. Verses 44-48 show their conversion.
In Acts 19, Paul preached Jesus Christ to the Ephesians. Verses 1 and 2 show that these were believers, for Paul asked them if they had “received the Holy Ghost since ye believed”. If you notice, the next two verses (3 and 4) show NO teaching of Christ’s death, buriel, and resurrection. That’s because they already believed it. It was THEN (vs 5) that “they were baptized in the name of the Lord Jesus”.
Then Paul laid hands on them, and they received the Holy Ghost. (vrs 6)
Read Acts 1:6. "When they therefore were come together, they asked of him, saying, "Lord wilt thou at this time RESTORE AGAIN THE KINGDOM TO ISRAEL?" They were inquiring as to THE KINGDOM and ISRAEL, not one word about the preaching of the cross.
I'm not going to go further into Cornelius until we can get through this part. It's just going to get mired. And if you cannot see this simple part, the rest will do nothing to help you, I'm certain. And I am not saying this in a rude way, Zuriel. It's just a fact. Until God's word is read EXACTLY as it is written, it will do no good to point these things out. You're reading what you THINK it says, or what someone told you it says, but not what it actually SAYS. Peter's sermon on the day of Pentecost is a prime example.
