Why is justification by faith essential for salvation?

Justification by faith is pivotal in salvation, as it positions faith in Christ as the sole means through which sinners receive righteousness. Romans 1:17 states that 'the just shall live by faith,' affirming that turning to Christ for salvation leads to being justified before God. This doctrine, emphasized by Martin Luther, distinguishes a vibrant church from a stagnant one, underscoring that faith in Christ is the means of receiving God's grace. Without this faith, individuals remain under condemnation, but faith invokes God's justifying grace.
