What does 2 Thessalonians 2:13 mean?
As Paul reflects on what God did in the Thessalonians' lives, he gives thanks constantly. They are his spiritual brothers in whom God's love abides. He is thankful specifically that God chose them from the very first to grant them salvation.This divine choosing does not rule out human accountability. The gospel summons sinners to believe on Christ, which Paul's readers did (1 Thessalonians 1:4–6). However, the Holy Spirit fills a significant role in salvation by setting sinners apart for salvation. In response to the work of the Holy Spirit, the Thessalonians had put their trust in the truth, the message of salvation that Paul and his fellow missionaries had preached in Thessalonica. Salvation is entirely by grace, but no one is saved unless he accepts it by faith as a gift from God. Paul wrote in Ephesians 2:8–9: "for by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast." And in Romans 6:23 Paul declared that eternal life is the gift of God "in Christ Jesus our Lord."
