What does the Bible say about pride and salvation?

In Romans 11, Paul cautions Gentile believers against boasting over the unbelieving Jews, stating that their salvation is solely due to God's sovereign mercy and grace. Pride causes us to overlook the reality that, without God's intervention, we too would be lost. Paul reminds us that salvation conditioned on Christ removes any grounds for boasting, as faith itself is a gift from God (Ephesians 2:8-9). Our assurance lies not in our deeds, but in the grace extended to us through Christ.
