How do we know that Christ's suffering was necessary?

The necessity of Christ's suffering is deeply rooted in the doctrine of atonement and the justice of God. According to Jeremiah 23:5, God promised to raise a righteous branch, emphasizing that justice must be satisfied for any transgression. Romans 3:25-26 expands this by explaining that God publically displayed Christ as a propitiation through faith in His blood, emphasizing that justice was upheld while providing mercy to sinners. If Christ had not suffered, the demands of divine justice would not have been satisfied, and humanity would remain under the curse of the law (Galatians 3:13). Thus, it was not merely an option but a divine necessity for Christ to bear the wrath of God in His suffering, fulfilling both the law and the prophecy in a single perfect act of obedience.
