κενός (kenos) means "empty," πλήρης (plērēs) means "full", and κοινός (koinos) means "common." Kenosis (the act of emptying) is the first thing we need before God. It is our humility. Then, we will be filled by the Spirit. With this Spirit, we can share a fellowship (koinonia) with others, based on common sense that we are all weak.
