God constantly loving his people and doing what he says he will do is spoken of as if faithfulness and trustworthiness were objects of which God has a large quantity.

Alternate translation: "always loving your people and very worthy of people trusting you" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-abstractnouns]])
