How do we know Christ crucified is the only way to salvation?

The certainty that Christ crucified is the only pathway to salvation is reinforced throughout the Bible. Paul's assertion in 1 Corinthians 2:2, where he declares he resolved to know nothing but Jesus Christ and Him crucified, epitomizes this doctrine. This perspective is rooted in the Old Testament typologies, as seen in the sacrificial lambs that foreshadowed Christ's ultimate sacrifice. Furthermore, Revelation 13:8 highlights Christ as the Lamb slain from the foundation of the world, illustrating that God's redemptive plan centers on Christ alone. Thus, Scripture consistently directs believers to place faith in Christ's atoning work as the sole means of salvation.
