Why is faith alone important in salvation?

Faith alone is emphasized in Reformed theology as the only means through which we receive the grace of God for salvation. John 6:29 reveals that the work God requires is to believe in the one He has sent, which indicates that reliance on faith, rather than works, is essential. Romans 1:17 states, 'The just shall live by faith,' showing that genuine faith is not merely intellectual assent but a deep trust in Christ's atoning work. Without this faith, we cannot access the grace that justifies and saves us.
