How do we know the gospel is the true path to salvation?

The validity of the gospel as the true path to salvation is anchored in the declaration of Romans 1:16, where it states that 'the gospel is the power of God unto salvation to everyone that believeth.' This message underscores the sufficiency of Christ's atoning work and the necessity of faith in Him for salvation. The scriptures affirm that there is no other means by which men can be saved, and that salvation is a gift of grace, not based on human works but solely on God's mercy and the redemptive work of Jesus Christ.
