Verse 11 is interesting, He is “ ‘the stone you builders rejected, which has become the capstone.’ The notes in my Bible says that the capstone unites the two sides of an arch and holds it together. Peter is talking about how the Jews had rejected Jesus, thus making Him the capstone that united us all in the church. Without Jesus there would be no church because it would not be able to stand on its own without everything He did to fulfill His purpose here on earth.
