Well technically The Holy Bible doesn't say when, so we don't know if it will be today, tomorrow, or in 100 years from now.
Or never is more likely.
The Holy Bible says that Earth is flat, was created 6000 years ago, and all fauna and flora was destroyed 4000 years are in a global flood.
If I were you, I would not worry about what the Holy Bible doesn't say, I would worry about what it does say.
No religious believer has ever been able to tell me why an infinite being has to ''wait'' to comeback and ''save us'' if he can do it any time he pleases and he already knows the future.
