The first ring is the close context, also called the immediate context: the surrounding words, the verses before and after the verse under consideration. For example, Peter’s speech on the Day of Pentecost includes the promise, “Everyone who calls upon the name of the Lord shall be saved” (Acts 2:21 cf. Joel 2:32). Nothing is more important than receiving salvation. We want to know more about how one calls to be saved. So, let’s continue reading to see how the context develops that promise. Acts 2:36-37 tells how Peter’s hearers are convicted of their sin. Cut to the heart, they cry out, “What shall we do?” Does Peter reply, “Just ‘call’ as I said before”? His answer goes into further detail:
Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit (Acts 2:37-38).
Being “saved” includes receiving “forgiveness” and “the gift of the Spirit.” And how do convicted sinners receive salvation? They must “repent” (decide to change) and “be baptized” (be immersed) for the forgiveness they need. This truth applies to “every one of you,” even to “all who are far off” (Acts 2:39). Acts 2:21 and its contextual details show how believers call on the Lord’s name for salvation.
