What role does faith play in a Christian's life?

In the Christian life, faith plays a central role as it is through faith that individuals believe in the finished work of Christ. 1 John 3:23 clarifies that God commands us to believe on the name of His Son, Jesus Christ, which signifies that faith is not only an intellectual assent but a deep trust in Christ's redemptive work. Faith also evidences a believer's love for God, as they are called to keep His commandments, which stems from the love He first showed us. This dynamic highlights that our faith is not a means to earn salvation but rather the outcome of recognizing God's grace and Jesus’s sacrifice.
