The gospel talks of two salvations, the salvation of John 3:16, “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life,” and the salvation of Acts 2:40, when Peter cried out to the crowd, “Save yourselves from this corrupt generation.”
The first salvation is about saving us from the penalty of our sins forever. The second salvation is about saving us from the influence of sin now. Salvation eternal and salvation now, the two great salvations included in the gospel message.
It started with John the Baptist and his “baptism of repentance for the forgiveness of sins” in Mark 1:4, and it continued with the apostles and their preaching in Luke 24:46-47, that “Christ will suffer and rise from the dead on the third day, and repentance and forgiveness of sins will be preached in his name to all nations.”
And that’s exactly what Peter preached in Acts 3:19, when he told his fellow Jews: “Repent, then, and turn to God, so that your sins may wiped out,” and verse 26: “When God raised up his servant, he sent him first to you (Jews) to bless you by turning each of you from your wicked ways.” It was the same message in Acts 5:31 too: “God exalted Jesus to his own right hand as Prince and Saviour that he might give repentance and forgiveness of sins to Israel.” And thousands of Jews believed it, that their sins had been forgiven forever and their lives could be straightened out in this life now.
That same message then went to the Gentiles in Acts 26:17-18 when Jesus sent Paul “to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.” That’s the first salvation, salvation eternal, the total forgiveness of their sins forever made possible by Jesus’ death. And then in verse 20: “I preached that they should repent and turn to God and prove their repentance by their deeds.” That’s the other salvation, salvation now, where real changes start happening in one’s life now.
Peter talks again about both salvations in 2 Peter 1, how God has made it possible for us to “escape the corruption in the world caused by evil desires,” verse 4. That’s the salvation we experience every day, but what stirs a person to live that salvation from the wrong ways and thinking of this world now is the ever present memory of being “cleansed from his past sins,” verse 9. He never forgets his salvation eternal either.
