Explanation:
He didn't just come to do miracles, he came to be an example of how we as believers should live and act (and we fall short every single day), but his death and resurrection, mean everything. Without those two things, we would, (1), not be saved from the sins and the bad things of this world, and (2), not be able to have life after death. You see, his death was to take all of our sins and wrongdoings upon himself (Because he loves us) so that we can be forgiven. There had to be a sacrifice of perfect blood so that we can be covered and forgiven forever if we just believe. His resurrection was so that he could show us his power and that he has the power over death, hell, and the grave.
I hope this helps, and if you have any questions, please ask and I'll answer to the best of my ability.
(I tried to give more, but it wouldn't let me... so I hope this is enough!)
