How do we know grace is free and not earned?

The nature of grace is that it is a gift, unearned and freely given by God. Romans 11:6 states, 'If by grace, then it is no more of works: otherwise grace is no more grace.' This underscores that any attempt to earn grace through our deeds transforms grace into a debt owed, rather than a gift. The widow of Sarepta and Naaman were both in desperate need, and their healing came solely by God's unmerited favor, not because of any action they took to deserve it. This principle is vital for understanding the unconditional love and mercy that God extends to His people, evidencing that salvation is all of grace.
