How is salvation achieved according to Christian doctrine?

Christian doctrine asserts that salvation is not based on human works or efforts, but is solely by grace through faith in Jesus Christ. 2 Timothy 1:9 clarifies this by stating, 'Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began.' This verse articulates that God's grace initiates salvation, underscoring the belief that it is part of His eternal purpose. This principle liberates believers from the despair of trying to earn favor with God through their deeds, affirming that genuine faith results in a transformation that reflects the character of Christ in their lives.
