Very well written and I agree with everything you write here. Many times people forget all the things Jesus talks about throughout his earthy ministry.

But brother I think you might be missing the forest for the trees.

Through all the important things Jesus talked about why He was here on earth, perhaps the most important thing He DID was die on the cross.

And Hebrews 9 attests to the fact that His death was all for the remission of sins. The entirety of the OT points to that.

So yes, the 18 reasons He talks about for life on earth and why He came are important, but the 1 specific reason He acted on was His death, burial, and resurrection.

Blessings.
