How do we know that salvation comes only through Jesus?

The exclusivity of salvation through Jesus is foundational to sovereign grace theology. According to Acts 4:12, there is no other name under heaven given among men by which we must be saved. This underscores the idea that no amount of human effort or religious observance can attain redemption; it is solely the work of Christ, who purchased our salvation with His own blood. Those who are fully aware of their lost condition depend entirely on a Deliverer capable of redeeming them, which Jesus embodies as the mighty Savior. His resurrection is a testament to His authority over death, solidifying that He is the only source of eternal life.
