“For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.”
King James Version (KJV)
5:19 As by the disobedience of one man many (that is, all men) were constituted sinners - Being then in the loins of their first parent, the common head and representative of them all. So by the obedience of one - By his obedience unto death; by his dying for us. Many - All that believe. Shall be constituted righteous - Justified, pardoned.
Ro 5:19 For as by one man's disobedience. By Adam's disobedience, all disobeyed and were counted sinners. So by the obedience of one. By Jesus' obedience, all are counted obedient, and hence, righteous. That is, all inherited penalty for Adam's sin is blotted out for the whole race. All who have not personal sins are held to be justified. Hence all infants are sinless. The basis of infant baptism is removed. Baptism is for those who have personally sinned.
