With Adam, his one act of disobedience impacted all, the whole human race. With Christ, His one act of obedience impacted all, the whole human race as both, were representative heads of the human race. Death came to all, including Adam, because of his sin. The penalty of sin, which is death, was paid by Christ by His death, the fullness of the payment guaranteed by His resurrection. The payment was made for all in the likeness of the sin of Adam. The application of the benefit of the death of Christ to each individual sinner is by personal faith in His person and work.
