Why is faith in Christ alone important for salvation?

Faith in Christ alone is essential for salvation as it recognizes that Jesus is the only mediator between God and man. The belief that He accomplished salvation through His death and resurrection is pivotal. In John 6:40, Jesus states that all who look to Him and believe will have eternal life. This emphasizes that salvation is not about human effort or works, but solely about trusting in Christ's finished work. This singular focus on faith in Christ guards against a false reliance on personal piety or moral goodness, ensuring that salvation is fully by grace.
