One of the great things about the Gospel of Thomas is that no body of man has had 2000 years to work it over, twist it, or weaponize it to support their view or to support their motives. Everything within the Gospel of Thomas is compared to the canonical gospels, and beyond weighing the truthiness of Thomas, it also introduces an new introspection into the other gospels as well. More on that later. Stevan Davies has written extensively on The Gospel of Thomas, and one his observations strikes me as extremely important. He says:
John’s Gospel contrasts this world with another world from which Jesus comes (cf., e.g., 8:23; 17:13-19). Thomas is not dualistic in this sense. For Thomas there is no contrast between this world and another world; rather Thomas contrasts this world as apprehended properly with this world not apprehended properly. Thomas is replete with sayings contrasting the condition of people whodo and who do not apprehend the world through the primordial light of the beginning. Those who do are full; those who do not are empty (Gos. Thom. 28). Those who do are united and filled with light; those who do not are divided and in darkness (saying 61). Those who do are wealthy (sayings 85, 110); those who do not are in poverty (saying 3). Those who do drink from Jesus and become like Jesus (sayings 13, 108); those who do not are drunk and do not pay attention to Jesus (saying 28).
