Passage
This is the stone which was rejected by you the builders, which is become the head of the corner.
This is the stone which was rejected by you the builders, which is become the head of the corner.
Acts 4:9 If we this day are examined concerning the good deed done to the infirm man, by what means he hath been made whole:
Acts 4:10 Be it known to you all and to all the people of Israel, that by the name of our Lord Jesus Christ of Nazareth, whom you crucified, whom God hath raised from the dead, even by him, this man standeth here before you, whole.
Acts 4:11 This is the stone which was rejected by you the builders, which is become the head of the corner.
Acts 4:12 Neither is there salvation in any other. For there is no other name under heaven given to men, whereby we must be saved.
Acts 4:13 Now seeing the constancy of Peter and of John, understanding that they were illiterate and ignorant men, they wondered: and they knew them that they had been with Jesus.
The verse centers on "stone", "rejected", "builders", "become", "head", and "corner". It is saying that the verse draws attention to "stone" and "rejected", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "Be it known to you all and..." into verse 12's "Neither is there salvation in any other...", so "stone" and "rejected" belong inside that flow. In Acts context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "stone" and "rejected" with trust shaped by these words, not by a vague optimism outside the passage.
