How do we know Jesus is our successful Savior?

Jesus is referred to as our successful Savior because He took upon Himself the sins of His people, fulfilling the demands of divine justice through His sacrifice. In Isaiah 53, it describes how He was wounded for our transgressions and bruised for our iniquities, demonstrating that His death was not meaningless but was the culmination of God's redemptive plan. Through His suffering, He atoned for all our sins, making it possible for us to be reconciled to God. Galatians 3:13 states that Christ redeemed us from the curse of the law, affirming that His work was sufficient to bring about our salvation.
