Why is faith crucial in receiving God's grace?

Faith is fundamental in the context of grace because it serves as the open hand that receives the gift God offers. Ephesians 2:8-9 indicates that we are saved through faith, not by works. This reflects that faith itself is not an achievement but a response to God's grace actively at work within us. Romans 10:9-10 further clarifies that belief in one's heart leads to righteousness, and confession with one's mouth leads to salvation. In essence, faith is driven by the grace of God and enables us to accept what we can never achieve on our own.
