is the concept of unfailingly remaining loyal
to someone or something and putting that loyalty into consistent practice, regardless of extenuating circumstances. It may be applied to a husband
who, in a sexually exclusive marriage, does not engage in sexual relationships outside of the marriage
, a customer at a restaurant who regularly dines there, or even to God
himself with regard to his perpetual love towards his children that is not dependent on their worthiness. It could also mean keeping to one's promises no matter the prevailing circumstances. Literally, it is the state of being full of faith
in the somewhat archaic sense of steady devotion to a person, thing or concept.
