Why is faith important in relation to God's grace?

Faith plays a vital role in the life of a Christian as it serves as the channel through which God’s grace is received. Ephesians 3:12 emphasizes that through Christ, believers have boldness and access with confidence by the faith of Him. This indicates that our faith is founded in the work of Christ who provides what we need, including the very faith to believe. Hence, faith is not something we conjure up ourselves but is supplied by Christ as part of His gracious provision. This emphasizes that salvation is entirely contingent upon His work, offering assurance to believers that they can approach God with confidence.
