stuck in stinkin' thinkin' about motivation

It has taken me quite a bit of thinking to identify stinkin' thinkin' about intrinsic motivation. The idea that intrinsic motivation is "scratching the itches of our soul" versus extrinsic, where putting forth effort to receive rewards from the world around us, is as far as I had taken it. However, in my book I am writing, I was faced with the question if intrinsics are ever carnal and if so, what is the difference between carnal intrinsics and and Grace intrinsics? The following is where I have landed. Its been an very interesting thought journey to get here. I would like anyone's thoughts on this exert from my book draft regarding clarity and completeness. You know - making sense of things is what the book is about :-)

I would suggest first that extrinsically motivated behavior is carnal minded in the sense that it requires exchange of one’s behavior for reward from the world around them. Intrinsically motivated behavior is a bit more complex. Whether the motivation is from a carnal mind or Kingdom mind depends on the nature of our intrinsics. If our purpose, meaning, and enjoyment in life are satisfaction gained from meeting our need to be significant through our own actions, we are intrinsically motivated to scratch self-serving itches and our well-being depends on the impact we make in the world around us. Viewing this through the lenses of Equity Theory of motivation, the carnal mind sees more effort is necessary to produce an outcome that is significant in their world, which creates for them a desired sense of happiness (referent). Making sense of intrinsic motivation through the Kingdom mind involves understanding the outcome of one's effort is independent of context (the worldly situation) and focused on the outcome of pleasing God, resulting in joy (referent). Apostle Paul says in his writings to the Corinthians that we seek (our intrinsic motivation) outcomes that are eternal and invisible resulting in an ambition to please God. Of course, we know from the famous passage in the letter to the Hebrews that without faith it is impossible to please God. Thus, we can contrast the carnal sense of intrinsic motivation from the Divine alternative using Equity Theory of motivation in following way:

It is interesting to note that there have been many books written to encourage people to seek purpose in their lives as their ultimate ambition. Some, like Buford’s “Halftime,” focus on significance not worldly success as a higher order need in our human existence. While I cannot speak to the authors’ sense-making assumptions that are at the root of theses messages, I can say that the appeal to significance to produce a happy and fulfilling life is carnal minded when our significance is defined by our impact on the world around us. This notion of significance as purpose is so stealth that many, many Kingdom dwellers are deceived to believe significance is their ambition, putting them in bondage to the results of their actions, not the faithfulness of them.
