Passage
For to you is the promise and to your children, and to all who [are] afar off, as many as [the] Lord our God may call.
For to you is the promise and to your children, and to all who [are] afar off, as many as [the] Lord our God may call.
Acts 2:37 And having heard [it] they were pricked in heart, and said to Peter and the other apostles, What shall we do, brethren?
Acts 2:38 And Peter said to them, Repent, and be baptised, each one of you, in the name of Jesus Christ, for remission of sins, and ye will receive the gift of the Holy Spirit.
Acts 2:39 For to you is the promise and to your children, and to all who [are] afar off, as many as [the] Lord our God may call.
Acts 2:40 And with many other words he testified and exhorted them, saying, Be saved from this perverse generation.
Acts 2:41 Those then who had accepted his word were baptised; and there were added in that day about three thousand souls.
The verse centers on "promise", "children", "afar", "lord", and "call". It is saying that the verse draws attention to "promise" and "children", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 38's "And Peter said to them Repent and..." into verse 40's "And with many other words he testified...", so "promise" and "children" 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 "promise" and "children" with trust shaped by these words, not by a vague optimism outside the passage.
