How do we know Christ's affliction was for our salvation?

The affliction of Christ was a necessary part of God's redemptive plan. As articulated in Psalm 22, Christ's suffering reaches beyond mere physical pain; it embodies the spiritual agony He experienced for the sins of His people. Matthew 27 illustrates the fulfillment of these prophetic words as the crowd mocked Him, echoing the psalmist's text. Christ’s crucifixion not only embodies His suffering but also ensures that He could declare victory over sin and death. Ultimately, through His affliction, Christ secured the salvation of the elect, proving that His suffering was not in vain but rather the means by which we are reconciled to God.
