God is very clear that he wants to rescue us from sin and to include us in a community that helps us put life together in a wholesome and truthful manner. But God is also clear that he saves us not just for our own sake but for the sake of the world. There is work to do in the world. One of the most revolutionary principles of Reformed Theology is the truth of our calling by God to be a participant in God's work in the world. Nothing is more ennobling.
Nothing is more demanding.
There is nothing dull or boring about the Christian faith. If your faith has felt dull and boring, then you have missed this third conversion to find your calling in God's work in the world. I have been richly blessed in my life. I had only a vague sense of what God had in store for me. It is obviously the right time to retire.
