After considering the end of grace, or its necessity for our final end, the essence and divisions of grace, St. Thomas next examines its cause, particularly its efficient cause (article 1) , and at the same time the disposition for grace on the part of the recipient (articles 2 and 3); this leads him to ask whether grace is equal in all men (article 4) and whether a person may know that he possesses grace (article 5).
