More than my fair share of the time I have sat back after pulling my weight and the weight of a few others on this or that task, and wondered, “Where is my thanks?” I of course never would admit to working for a thank you; it is always for the good of this or that. But that is hypocrisy.
I would rather not count the sermons I have heard about forgiving people 70 times 7. I have heard hundreds of people talk about faith like a mustard seed. I have never even heard people discuss what you find only one verse later. In Luke 17:7-10, Jesus calls me out in my error. “Suppose one of you had a servant plowing or looking after the sheep. Would he say to the servant when he comes in from the field, ‘Come along now and sit down to eat’? Would he not rather say, ‘Prepare my supper, get yourself ready and wait on me while I eat and drink; after that you may eat and drink’? Would he thank the servant because he did what he was told to do? So you also, when you have done everything you were told to do, should say, ‘We are unworthy servants; we have only done our duty.’ “
How easily we forget what we were commanded to do – Go into the world and preach the Good News. We get hung up wondering where our thanks are coming from for this or that little task; there is a whole world out there needing the love that only God can give and we bicker about a word of thank you for doing exactly as we are expected. Maybe your professors are a little different than mine, but none of mine coo and fuss over me turning my papers in on time. It is expected. When people dare to step forward and own up to their faith, we congratulate them and get excited.
That is such a mistake. We shower praise upon an unworthy person for doing just as they are expected. In an entire lifetime we could not unwrap all of what Jesus is saying in these verses, but I know this. If I ever hear about you sharing your faith with another, I will let you know you did a good job – but then I will ask a simple question, “What about him? Or her, does she know?” Each time we discuss salvation there should be a great party and rejoicing beyond compare – while we were yet sinners Christ died for you and you and you and ……
Celebration of such Love and returning it does not expect a thank you. It makes no sense to expect God’s thankfulness that we have accepted His gift, and He is after all the one whom we serve.
