Again, you're taking things out of context. Isaiah 53 specifically mentions peace, justification, and intercession while Ezekiel is illustrating a sign of the impending siege of Jerusalem (Ez 4:7). Ezekiel is about judgment and destruction upon the city and his lying on his side doesn't justify anyone, rather it is an illustration of the coming judgment on the land. Isaiah is all about promise and peace and justification and life based upon the one who bore the sins. Ezekiel doesn't bear the sins as to justify anyone but as a sign to the people of judgment of sin.
I am aware of the contextual and thematic differences between Isaiah 53 and Ezekiel 4.
But the idea of one man "bearing the sins" of others can only mean the same thing. You're just arbitrarily claiming Ezekiel "bearing the sin of others" is somehow different from Jesus "bearing the sin of others".
Ezekiel doesn't bear the sins as to justify anyone but as a sign to the people of judgment of sin.
I know. But if Ezekiel bearing sins was just a sign, and doesn't mean he literally bore the sins of people, then the same applies to Jesus as well.
After all, every man is responsible for his own deeds and will be judged according to his deeds. There's no question of one man literally bearing the sins of others.
