Or course, we sin much much more. I think I do at LEAST once a minute. I won’t do the math, but I know that Christ Jesus bore my sins, became sin for me, and the Father turned His back on Him - for all the sins I have and will commit. And not just mine, but for all of His people. And then, He said, It is finished.
We cannot fathom the extent of even our individual sins that He took on, much less all the sins of all His people. Hallelujah. What a Savior!
Everything about us is corrupted with sin, which is why Isaiah says that all our righteous deeds are as filthy rags in god’s sight.
Even our motivations for doing things are rarely pure. How often do we make decisions based on what’s best or convenient for us, or maybe in awareness that we may get some reward for it?
I’d hazard a guess that we are all far more self-serving than we’d care to admit.
