13 But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God from the beginning chose you for salvation through sanctification by the Spirit and belief in the truth, 14 to which He called you by our gospel, for the obtaining of the glory of our Lord Jesus Christ. (2 Thessalonians 2:13-14, NKJV)
Paul was thankful to God for his brethren because they are participants in God’s election in Christ (verse 13). This was not a predetermining of each soul being either saved or lost, but of God’s choice to save sinners in Christ (Ephesians 1:3-4, 11:12). God uses the gospel to call sinners to redemption’s glory. Jesus said the Father draws sinners to Himself by teaching them His will, “It is written in the prophets, ‘And they shall all be taught by God.’ Therefore everyone who has heard and learned from the Father comes to Me” (John 6:44, 45). God does not call people through personal revelations, visions and experiences. He calls sinners “by our gospel” (that is, the gospel preached by the apostles, Mark 16:15). God’s call to salvation is for everyone and the same to everyone. There is only “one faith,” the gospel preached by Christ’s apostles (Galatians 1:11, 23; Acts 24:24). Notice the linkage between the gospel and salvation. The gospel that calls us to salvation produces faith so that we may be made holy (sanctified) and obtain the glory of Christ. To suggest we can be saved with the gospel nullifies the “sanctification of the Spirit,” the “belief in the truth,” obtaining the glory of Christ.
