How do we know the doctrine of salvation through Jesus is true?

The doctrine of salvation through Jesus stands firm on the biblical witness and the historical reality of His life, death, and resurrection. 1 Corinthians 1:18 emphasizes that 'the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.' This illustrates that the message of Christ's atoning sacrifice has a profound, life-altering effect on those who believe, testifying to its truth. Historically, Jesus fulfilled the prophecies concerning the Messiah, and his resurrection from the dead provides the ultimate verification of His claims. The consistent experience of believers receiving new life through faith in His name underscores the truth that salvation is indeed found in no other name but His.
