Reformed Baptists teach salvation according to the Calvinist framework articulated in the 1689 London Baptist Confession and grounded in the TULIP doctrine. Salvation begins with God's unconditional election of individuals to eternal life before the foundation of the world, not based on foreseen faith or works. This election is God's free, sovereign, and immutable choice.

Through Christ's death, redemption is accomplished for the elect particularly — the doctrine of limited atonement (particular redemption). Salvation is entirely monergistic: God regenerates the spiritually dead sinner through irresistible grace, creating spiritual life and capacity for faith. Justification — the legal declaration of the believer's righteousness based on Christ's imputed righteousness — follows faith, which itself is a gift of God. Faith is not a human work contributing to salvation but a fruit of God's prior grace.

The 1689 Confession affirms the perseverance of saints: all truly born-again believers will be preserved in faith and brought to final salvation through God's unchangeable decree and the Spirit's continual work. Apostasy signifies one was never truly regenerate. This assurance is grounded not in human strength but in Christ's intercession and God's covenant faithfulness.
