Why is believing in Jesus's name important for Christians?

Believing in the name of Jesus is foundational to the Christian faith, as His name embodies His authority and the fulfillment of God's promise of salvation. According to Acts 3:16, it is through faith in His name that individuals receive healing and restoration. This underscores that salvation and life are granted only through Christ. Romans 10:13 explicitly states that whosoever shall call upon the name of the Lord shall be saved, further emphasizing the necessity of faith in His name for eternal life.
