Prehistoric plans

just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, - Ephesians 1.4-5

What do you think about when you hear the word 'prehistoric?' The first thing that comes to my mind is dinosaurs and cavemen. I know, that is not right, but that is what I think of. But then I have to ask 'what is prehistoric?' How can anything be pre-history for the believer? We have history from, literally, Day One forward. Our history starts with 'In the beginning God...' How do we go before the beginning? 

But we do know some stuff from before the beginning. This passage has a key teaching for us from 'before the beginning.' 

Before the foundation of the world God chose that His elect would be holy, without blame, and adopted as His children. I am purposefully skipping who the elect are, except to say that they are those who have trusted Christ. 

God ordained, before the beginning, that his people should live holy and blameless lives adopted as His children. 

Holiness though has seem to become passé. We like the idea of being adopted as God's children, but are not so sure about this holiness bit. Sometimes it seems like we want to be as much like the world as we can instead of walking in God's holiness. It seems to be more of an attitude of 'what can I get away with?' instead of 'how can I live holily?' 

God's plan for us, before the beginning, was that we live holy lives. Do our lives reflect that holiness?
