How do we know salvation is through Christ alone?

Throughout scripture, including Titus 3:5-6 and Ephesians 2:8-9, it is clearly established that our salvation is not based on our works but solely on the kindness and love of God through Jesus Christ. The New Testament emphasizes that redemption and forgiveness of sins are gifts received through faith in Christ, reinforcing the truth that we cannot earn our way to salvation. This doctrine reflects the sovereign grace of God who chooses to bestow grace upon His elect for Christ's sake, aligning entirely with the theology that prioritizes God's glory above all.
