How do we know that faith will lead to salvation?

The assurance of salvation through faith is grounded in the sovereignty of God, who grants faith as a gift. Ephesians 2:8-9 states, 'For by grace you have been saved through faith, and that not of yourselves; it is the gift of God.' Jesus Christ, being both the author and finisher of faith, establishes that our belief is not merely a human effort but a divine enablement. As we trust in the promises of God and the completed work of Christ, we can be certain that our faith will ultimately lead to the salvation of our souls, being fully accomplished in the last day as evidenced in Philippians 1:6.
