If Adam's sin brought death to all automatically, shouldn't the Second Adam's salvation automatically bring life to all?

The parallel between Adam and Christ is not symmetrical. God made Adam the head of the human race so that whatever Adam did would affect all his descendants. Adam knew the consequences of sin before he disobeyed, and God bound all humanity to his decision. This is not unfair, because God could have made us share equally in his obedience if he had remained faithful. By his rebellion, Adam humiliated God before all creation. The scale of the offense required a redeemer who was both divine and human. Justice demanded that the same nature that sinned should make satisfaction, yet the offense was so great that only a divine person could offer reparation. Christ’s sacrifice not only removed Adam’s curse but raised humanity above its original state. We are not restored to Eden; we are elevated to union with the divine Son. God’s justice and mercy meet in the Cross. Salvation is offered to all, but each person must freely cooperate through faith, baptism, and perseverance. Grace is sufficient for everyone, but it is applied only through the means God has ordained.
