I suppose that temporal productivity would be to produce things of value to the temporal world.  It follows then that spiritual productivity would be to produce things that are of value in the spiritual world.  So, to be temporally productive might mean that we make rope and tea cups and gold rings and antibiotics and blenders and houses and other such things.  To be spiritually productive we have to consider the breadth of the spiritual world and the things that might be valuable in it. For one part of the spiritual world it might be valuable to produce anger and pride and lust and envy and selfishness.  To do so would make you a valuable partner in one major corner of the spiritual world.  However, it would make you an enemy in another part of the spiritual world.

We tend to forget about the breadth and the opposing values that are part of what we call spiritual.  In our thoughtlessness we gush all about how someone is “sooo spiritual”, as though to be active in the spiritual realm in any capacity is to be considered good.  It is easy, but foolish, to get confused in that way.  It is easy because we are accustomed to thinking in temporal terms.  Gold made in Russia, remains valuable in any other part of the world.  A plow made by machine in Germany, remains a useful tool for turning the ground in Afghanistan.  The temporal world only measures a certain kind of value and that value is universal throughout the temporal world. 

In the spiritual world, however, there is constant spiritual warfare.  The tools and things of value in one part of the spiritual world are loathsome in another part.  The devil hates the very ideas of charity and kindness and mercy and meekness and he seeks to destroy those things and convert them into the coin of his realm.  This is one of the things that makes a polytheistic or spiritually diverse society so difficult to manage.  Things that are considered good in one part of it are spit upon by another part of it.  Serious conflict arises from such things.

So, now that I have argued with the phrasing of the question, let me modify the question.  What does Christian productivity look like?  As Christians, what did Christ our Lord ask of us?  He asked us to love one another; even to love our enemies. He asked us to “Make (Christian) disciples of all nations.”  He asked us to invite God into their hearts and minds and lives that they may be changed, by God, over time and made Holy according to Christian standards.  In short, Jesus asked us to be fruitful.

“I am the vine and you are the branches”, so declared Jesus to his disciples.  We are to be fruitful.  That happens two ways as illustrated by the metaphor of the grapevine.  First, we are to produce more grapes.  We are to bring more people into the vine.  That is called Evangelism.  Second, we are to make of the existing grapes, better grapes.  WE are to make grapes that have more of the characteristics of good grapes.  That is called Discipleship.

In order to be productive in the Christian sector of the spiritual realm we must make more and better Christians.  Starting with ourselves.  It really is just that simple.
