There are many instances of how God's power worked mightily in Peter, through the prayers of Jesus, to strengthen Christ's church. God instructed Peter that the Gospel was not just for Jews, but for despised Gentiles as well. When the Lord instructed Peter to go to Cornelius, Peter began to discern the true extent of Christ's revelation to him: that he must no longer separate himself from Gentiles as unclean persons, as the Jews did, because God would open the Gospel up to them also! The salvation of the Gentile Cornelius at God's command was bound to result in negative repercussions in the church at Jerusalem. Ethnic supremacy rises up whenever an exclusive privilege is opened up to others! The cry arises, "but they are not like us!" Cultural and ethnic clashes rose to the surface, and some Jewish believers objected to Peter's having consorted with uncircumcised Gentiles and even eaten with them! But this had been Peter's immediate objection when he told the Savior, "Not so, Lord!" The unthinkable things that had transpired, had been accepted by Peter, with the evidence of the Holy Ghost filling the new Gentile believers, so Peter was well suited to answer the demands for ethnic and religious separation that arose at the Jerusalem church. Peter related the entire sequence of events to the objectors, in particular Christ's command that Peter not call anything unclean which Christ has made clean. Peter had obeyed the Holy Ghost, doubting nothing. This itself was a rebuke to those who now insisted on second guessing Peter's actions and the Holy Ghost's commands to him. The Spirit's commandment trumped all their objections!
