The meaning of Christ's second coming

Look at the scripture:

John 12:47 If anyone hears what I say and doesn't keep it, I won't judge him. I'm not here to judge the world, but to save it.

John 12:48 Those who reject me and do not accept my words will be judged, which is what I said, and will be judged in the last day.

It can be seen from the Bible that Jesus came for the first time to "save the world" and Jesus came again to "judge the world".

Anyone who "rejects Jesus and doesn't accept his words" will be "judged at the last day" when Jesus comes again.
