While your title certainly has some truth to it (I think all sin can be rooted in unbelief); the comments and even Calvin points to a lack of thanksgiving as perhaps the foundational sin of Adam.

I think I can trace many of my own sins back to a lack of thanksgiving. What I have is never enough or its too much.

My car is not big enough and I am paying too much for gas.

Modern Calvinists have lost Calvin’s category of rejecting what was offered.

Their unbelief also exhibited ingratitude, as they failed to note what good they had been given. They wanted more.

Thanks for this. Gratitude plays a tricky role in popular Reformed thinking. Often it is portrayed as the engine that grace goes in (like gasoline) that produces obedient work. God was gracious, we were grateful, and therefore we respond in good works. Although I haven’t worked it out tightly with particular scriptural texts, it seems to me that gratitude is a gift alongside and parallel to our good works. It flows from our faith as works do. This post made me think that the reverse also might be true. Not only does unbelief / lack of faith produce disobedience, it produces the specific parallel”ingratitude.”
