How do we know Christ's work of salvation is true?

The truth of Christ's work of salvation is established by the fulfillment of Scripture, His miraculous resurrection, and the continued testimony of the Christian experience. The apostles proclaimed that Christ came to destroy the works of the devil and to grant freedom from sin, as illustrated in Romans 8:3, which states that God sent His Son to deal with sin in the flesh. Furthermore, His resurrection not only proved His divine authority but also affirmed that He has conquered death on behalf of all who believe in Him. The transformative power of the Gospel is consistently witnessed in the lives of believers, who experience a changed heart and are empowered to live righteously by the Spirit. Together, these elements create a solid foundation for the truth of Christ's salvific work.
