The Significance of Activity?

During my long and exhausting week last week, I thought a lot about the significance of our activity. I guess I think a lot about being busy vs. being productive. It seems to me that we are very busy - people I mean. We are busy. We are consumed with activity. Even in the best areas of our lives, like family and church, we are largely consumed by activity.
Activity is necessary to getting things done, and there is nothing wrong with it in and of itself. It just seems to me that with all of our activity, we ought to be getting more done. I admit we are doing a lot, but what is it that we are doing exactly? What is the significance of what it is we are doing? I am afraid that at the root of most of what we do is staying busy, being active. It is as if we equate life to activity and growth to busyness.
The question of significance is the issue. Apart from the purposes of God and His glory, nothing we do is significant. It is all just busy activity apart from some eternal sense of significance. It is all just passing away. It is all just filthy rags, or wood, hay and stubble.
It is no wonder that so many of our churches struggle with the commitment level of our people, the effectiveness of our ministry and the making of true disciples. We are too busy. We are doing too many good things and not doing the most significant things, the best things, well enough. What is it that has eternal significance? What are the things in our lives that God has said are significant?
That is the ultimate question, I think. The things in our lives that are significant, the things that last and grow and produce fruit, are not the things that we think are important, or the things that our culture (secular or spiritual) deem important. The things that are significant are the things that God has given significance as part of His purpose and plan, the things that glorify Him most and allow us to enjoy Him most fully.
I find I am very comfortable in activity, but I do not delight in it. I delight in the Lord and all of my activity should flow out of that delight, and yes, should be confined to it. Otherwise, I am busy doing things that are by nature less delightful and less significant. Why live life settling for less than God's best for my life?
