Why is understanding the distinction between evidence and cause of salvation important for Christians?

The distinction between the evidence of salvation and the cause of salvation is crucial because many people mistakenly believe that their willing acceptance of Christ is what secures their salvation. However, Scripture teaches that salvation is entirely a work of God's grace, and the willingness to receive Christ is merely the evidence of that work. This understanding protects Christians from the false belief that they can initiate their salvation through works or decision-making, which undermines the foundational truth of grace. It assures us that our salvation rests solely on Christ's finished work and not on our efforts.
