How do we know Jesus Christ is the Savior?

The assurance of Jesus Christ as the Savior lies firmly in the scriptural testimony that spans both the Old and New Testaments. In John 3:16, it states, 'For God so loved the world that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.' This demonstrates God's initiative in salvation, affirming that Jesus came into the world with a salvific purpose. Throughout the Gospel accounts and epistles, the narrative consistently upholds that Jesus' mission is to redeem His people from their sins, culminating in His sacrificial death and victorious resurrection. This is further confirmed by His many declarations and prophecies that align with His work as the Redeemer.
