What is the significance of faith in Jesus for salvation?

The significance of faith in Jesus cannot be overstated; it is the means by which individuals receive salvation. In John 14:6, Jesus declares, 'I am the way, the truth, and the life; no one comes to the Father except through me.' This underscores that faith in Christ is not merely an intellectual assent but a deep, personal trust in His work and identity as Savior. The thief on the cross exemplifies this faith, recognizing Jesus’ lordship and authority even in his dying moments. His faith led to immediate assurance of salvation, demonstrating that true belief can spring forth even in the direst circumstances. For Christians, this reinforces the understanding that salvation is by grace alone through faith alone, as affirmed by the Reformation's core tenets.
