I will raise them up at the last day.
But doesn't St Paul tell us that "all will be raised"? This phrase has been used earlier in verse 40 in the context of believing in him.
I think that the emphasis here is that we don't believe in the way that we believe in the sky being blue - if it were red I would believe that too - in a way that nothing really depends on it. It means believing with an intesity that trusts absolutely.
As for being raised by Jesus this means being raised as one of his own. Sure, all will be raise but some for glory and some for destruction.
