How do we know that Christ's sacrifice was for sinners?

In the story of Samson, we see a foreshadowing of Christ, where Samson's union with a Philistine woman symbolizes the union of Christ with sinners. Just as God chose a bride from the enemies of Israel, Christ chose to have a relationship with His people despite their sinful condition (Romans 5:8). This narrative illustrates the depth of God's love, as He willingly sacrifices for those who do not deserve it, revealing the profound truth that Christ's mission was to deliver His people from bondage and sin, thus confirming that His sacrifice was indeed for sinners.
