Very few of us have missed out on the experience of working long and hard on a project or endeavor, only to find that all of our work was useless. I remember working many months on a project, only to have it scrapped at the last minute by management higher up. Our team was never told their reasons or criterion. Such is life. Of this we may be sure, however, we never need to wonder if we are (or are not) laboring in vain in the gospel. Invest twelve short minutes with us as we take a refresher course on how to make sure our lives and ministries actually add up to eternal good!
