Rabbi Levi Yitzchak of Berdichev (1740-1810) wrote in his Torah commentary, Kedushat Levi, about four kinds of righteous people. The first serves God with great devotion, but is content to concentrate on his/her own spiritual growth. The second kind of tzadik both serves God and strives to bring others, even the wicked, closer to God as well. The third tzadik, does not recognize his or her spiritual power and does not attempt to change God’s decrees, while the fourth tzadik has the spiritual awareness and inner humility to argue humbly with God to reverse a Divine judgment.
