I think as you see in these verses the steady decent from Bad to worst . Yes what they believed was critical to their salvation . As it is today . God is not mocked .22Professing themselves to be wise, they became fools,
23And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24¶Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25Who changed the truth of God into a lie , and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
