I didn't say that holy and blameless is not related to salvation, what I am saying is that Paul's words do not say anything about the election of people to salvation specifically; if it had it would say something like "For he chose us to be in him before the creation of the world." But he doesn't say that, he says that we, the church, we're chosen to be holy and blameless (by being) in him.
Be careful, ReformedGuy, you're getting close to proof-texting! ? My observation is based on a more holistic approach to interpretation, in other words, I am using one verse to give insight into the meaning of another. Jesus is making a factual statement about the group of people who would, in the end, be raised up on the last day. It makes no statement concerning how God gives them to Jesus, he just say "all that the Father gives me" will come and Jesus will raise them up on the last day. I would caution you that there is nothing about the predestinating decree of God either, so I find you to be importing that idea from elsewhere. Just sayin', my brother!
