How does Peter's vision relate to God's plan for salvation?

Peter's vision described in Acts 10 illustrates the radical inclusion of Gentiles into God's salvific plan. Initially, Jews viewed Gentiles as unclean and separate from God's promises. However, the vision revealed that God does not show partiality; what He has cleansed should not be considered common or unclean. This revelation was pivotal, as it prepared Peter to understand that the gospel was for all nations, fulfilling God's promise of salvation inclusive of Gentiles. This change highlights the universal scope of Christ's redemptive work, affirming that through Him, all can be reconciled to God, regardless of ethnicity.
