Passage
and Peter said unto them, `Reform, and be baptized each of you on the name of Jesus Christ, to remission of sins, and ye shall receive the gift of the Holy Spirit,
and Peter said unto them, `Reform, and be baptized each of you on the name of Jesus Christ, to remission of sins, and ye shall receive the gift of the Holy Spirit,
Acts 2:36 assuredly, therefore, let all the house of Israel know, that both Lord and Christ did God make him--this Jesus whom ye did crucify.'
Acts 2:37 And having heard, they were pricked to the heart; they say also to Peter, and to the rest of the apostles, `What shall we do, men, brethren?'
Acts 2:38 and Peter said unto them, `Reform, and be baptized each of you on the name of Jesus Christ, to remission of sins, and ye shall receive the gift of the Holy Spirit,
Acts 2:39 for to you is the promise, and to your children, and to all those afar off, as many as the Lord our God shall call.'
Acts 2:40 Also with many more other words he was testifying and exhorting, saying, `Be saved from this perverse generation;'
The verse centers on "Spirit", "peter", "said", "reform", "baptized", "each", "name", and "jesus". It is saying that the verse draws attention to "Spirit" and "peter", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 37's "And having heard they were pricked to..." into verse 39's "for to you is the promise and...", so "Spirit" and "peter" 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 "Spirit" and "peter" with trust shaped by these words, not by a vague optimism outside the passage.
