How do we know salvation is solely through Christ?

The exclusivity of salvation through Christ is foundational in the Scriptures. Acts 4:12 asserts, 'Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.' This emphasizes that the work of redemption is completed in Christ alone. The sacrificial death of Jesus, described as necessary according to the scriptures, underscores that individuals cannot achieve salvation through their efforts or through any other means. Our righteousness must come from Christ, as He is the appointed sacrifice for our sins according to God’s predetermined plan.
