Discipleship is great, but Paul encourages the Philippians to take ownership of their own walk with Jesus, even when Paul is not there. When we take ownership, we are walking with Jesus and his Spirit and then, we are to do the same as Paul, by walking with others, and pointing them to Jesus, that they would do the same. That way, we are participating in building Gods kingdom, here on earth. Is that not a beautiful way to see what gods will is in our life?
