FAITH is a word with many meanings. It can mean faithfulness (Matthew 24:25). It can mean absolute trust, as shown by some of the people who came to Jesus for healing (Luke 7:2-10). It can mean confident hope (Hebrews 11:1). Or as James points out, it can even mean a barren belief that does not result in good deeds (James 2:14-26). What does Paul mean when, in Romans, he speaks of “saving faith?”
We must be very careful to understand faith as Paul uses the word because he ties faith so closely to salvation. It is not something we must do in order to earn salvation–if that were true, then faith would be just one more deed, and Paul clearly states that human deeds can never save us (Galatians 2:16). Instead, faith is a gift God gives us because he is saving us (Ephesians 2:8). It is God’s grace, not our faith, that saves us. In his mercy, however, when he saves us, he gives us faith–a relationship with his Son that helps us become like him. Through faith he gives us, her carries us from death into life (John 5:24).
Even in OT times, grace, not deeds, was the basis of salvation. As Hebrews points out, "it is not possible for the blood of bulls and goats to take away sins’ (10:4). God intended for his people to look beyond the animal sacrifices to him, but all too often they instead put their confidence in fulfilling the requirements of the law–that is, performing the required sacrifices. When Jesus triumphed over death, he cancelled the charges against us and opened the way to the Father (Colossians 2:12-15). Because he is merciful, he offers us faith.
