How do we know that Jesus fulfills God's plan for salvation?

The fulfillment of God's plan for salvation through Jesus is evidenced in His life's work and His sacrificial death. Scripture reveals that Jesus obeyed the law in every detail, leading to His role as our substitute. His unique capability to take on the penalty for sin and rise again validates the truth of His mission. Hebrews 10:12-14 underscores that He, having secured eternal redemption, now intercedes for His people at the right hand of God, proving His victory over sin and death and the complete sufficiency of His redemptive work.
