We are assured of salvation by recognizing our complete reliance on God's grace and the sufficiency of Christ's work on the cross.
Salvation by grace is a fundamental tenet of Reformed theology and is rooted in the biblical teaching that we are saved not by our works but by faith in Christ alone. Ephesians 2:8-9 underscores this doctrine by stating that it is by grace we have been saved through faith, and this is not from ourselves; it is the gift of God. This means our salvation is entirely dependent on God's sovereign choice and Christ's righteous work. Moreover, our assurance comes from the consistent work of the Holy Spirit within us, making us willing to believe and persevere until the end, which points to the reality that our salvation is rooted in grace from beginning to end.
