Resurrection means to rise from the dead. This is how one can be born again, when we will be given new bodies. Think about it for a few minutes after I post this before you respond, just a few minutes it doesn't have to be long. We will rise out of the grave, we will be given new bodies, we will literally be born again. This is when we will be saved, this is the salvation of God, this is his promise throughout the scriptures, this is what all the heroes of the Bible hope for. It is hope, it is faith because it has not happened yet, it is not seen yet, this is why it is faith.
