Why is it important for Christians to believe in salvation through Jesus alone?

Understanding that salvation comes only through Jesus is central to the Christian faith. This belief upholds the doctrine of grace, affirming that it is not by our works or merit that we are saved, but solely through Christ's atoning sacrifice. Philippians 1:6 reassures us that He who began a good work in us will complete it, emphasizing God's faithfulness in our salvation journey. This truth prevents the distortion of the Gospel and maintains the integrity of the doctrine of justification by faith alone. It is essential for Christians to proclaim this truth to ensure that others may also know the saving grace available through Jesus.
