The issue of salvation “by grace through faith” and “not of works” (Ephesians 2:8) has challenged people, who find themselves on either side of the fence. The issue, simply, arises from the nature of the apostle Paul’s writings which, as the apostle Peter admitted, contains “some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures” (2 Peter 3:15-16).
Thus the divide between those who believe and teach that salvation is by grace alone — without works — and those who believe and teach that salvation is by grace — plus works.
