How do we know the work of Christ is true?

The work of Christ is substantiated by His perfect obedience to God's law and His sacrificial death on the cross. Hebrews 2:9 states that He tasted death by the grace of God for every man, indicating His role as a substitute for sinners. Additionally, His resurrection from the dead serves as a powerful testimony that validates His claims and His work of salvation. The wisdom of God throughout Scripture points to Christ's redemptive work, fulfilling the covenant promises made to humanity.
