Yes, Yeshua primary accomplishment was becoming the Passover Lamb, sacrificed from the foundation of the world! And He came to be a _witness_ to the Truth; witness here being evidence or representing it. YHVH’s Word is never ending Truth and Yeshua is the Truth made flesh. Learning is virtually impossible by words alone, at some point most folks need to see examples of the matter. Yeshua is the perfect example, living everything Torah says; being Torah in action, for us to see and follow.
