What does the phrase 'salvation's of the Lord' mean?

'Salvation's of the Lord' encapsulates the belief that God alone is responsible for the salvation of His people. This phrase highlights the central tenet of the Reformed faith, which asserts that God’s grace is the ultimate cause of a person’s salvation. It signifies that human effort or merit does not play a role in salvation, aligning with the teachings in Ephesians 1:4-5 where it's revealed that God chose us before the foundation of the world. This doctrine positions salvation as an act of divine grace, underscoring the necessity of understanding Christ's work on the cross—where His blood was shed to satisfy divine justice. Consequently, believers are called to have faith in the Lord Jesus Christ, who is the means through which salvation is realized.
