Here's a great quote from John Piper on the doctrine of election:
"Election...is unconditional in that there is no condition man must meet before God chooses to save him. Man is dead in trespasses and sins. So there is no condition he can meet before God chooses to save him from his deadness. We are not saying that final salvation is unconditional. It is not. We must meet the condition of faith in Christ in order to inherit eternal life. But faith is not a condition for election. Just the reverse. Election is a condition for faith. It is because God chose us before the foundation of the world that he purchases our redemption at the cross and quickens us with irresistible grace and brings us to faith" (Sermon manuscript What We Believe About the Five Points of Calvinism, desiringgod.org).
