Deuterocanon

Wisdom of Solomon 6:18

12 Wisdom is radiant and unfading, and she is easily discerned by those who love her, and is found by those who seek her. 13 She hastens to make herself known to those who desire her. 14 One who rises early to seek her will have no difficulty, for she will be found sitting at the gate. 15 To fix one's thought on her is perfect understanding, and one who is vigilant on her account will soon be free from care, 16 because she goes about seeking those worthy of her, and she graciously appears to them in their paths, and meets them in every thought. 17 The beginning of wisdom is the most sincere desire for instruction, and concern for instruction is love of her, 18 and love of her is the keeping of her laws, and giving heed to her laws is assurance of immortality, 19 and immortality brings one near to God; 20 so the desire for wisdom leads to a kingdom.

Athanasius On the Incarnation of the Word 4:6

6 For man is by nature mortal, inasmuch as he is made out of what is not; but by reason of his likeness to Him that is (and if he still preserved this likeness by keeping Him in his knowledge) he would stay his natural corruption, and remain incorrupt; as Wisdom says: The taking heed to His laws is the assurance of immortality; but being incorrupt, he would live henceforth as God, to which I suppose the divine Scripture refers, when it says: I have said you are gods, and you are all sons of the most Highest; but you die like men, and fall as one of the princes.
