Salvation is through faith because the Bible explicitly states that it is a gift from God, not based on our works (Ephesians 2:8-9).
The assurance of salvation through faith is rooted in scripture, particularly Ephesians 2:8-9, which proclaims that we are saved by grace through faith, and that not of ourselves; it is the gift of God, not of works, lest any man should boast. This reinforces the idea that human efforts cannot secure salvation. Moreover, in Philippians 1:29, it is emphasized that it has been granted to us to believe in Christ, highlighting that even our ability to believe is a divine gift. Faith is not just a response to God's grace; it is itself a work of grace in the believer's heart.
