I don't see that "ALL who believe" requirement in this scripture.Adam #2, came to restore to "ALL who believe", the spiritual union Relationship to God, that Adam lost because of sin.
Romans 5:18-19
Consequently, just as one trespass resulted in condemnation for all people,
so also one righteous act resulted in justification and life for all people.
19 For just as through the disobedience of the one man the many were made sinners,
so also through the obedience of the one man the many will be made righteous.
