How do we know Christ's suffering was necessary for salvation?

In the context of redemptive history, Christ's suffering was both necessary and predestined. As highlighted in Hebrews 2:17, He became like His brethren to make atonement for our sins. The severity of His distress is underscored by the intensity of God's wrath that was directed toward sin, which Christ absorbed on our behalf. This sacrificial act satisfied God's justice and rendered us righteous, allowing us to approach Him boldly in worship. His suffering demonstrates the immense love and sacrifice required for our redemption, making it integral to our understanding of the gospel.
