When we read this, it sounds almost as though Nehemiah is mocking Sanballat and Tobiah, and taunting them, because he is doing the very thing they don't want done: the walls of Jerusalem are to be built up and restored, the city made defendable. The enemies roundabout don't want that, so he seems to be mocking them, calling it a great work, and of course because we are on Nehemiah’s side in this matter, we rather like the sound of it.
That should always be the response of Bible loving people when anybody tries or seeks to negotiate with them, who isn't one of them. That's the principle and Nehemiah applied it. ‘We have nothing in common. What union, what interaction has light with darkness?’ Of course I have no cause to go and meet these men and to concede anything to them of any kind.
This is a marvellous motto text for all of us, and it applies in so many ways. If you're young and your friends come to you and they say, ‘Let's go here’, or ‘Let's go there’, and it's an evening too many, or it's a regular fixture, and they say, ‘Let's all get together in a crowd and have a jovial time together’, remember you are a child of God. You have given your life to him. You've yielded yourself entirely to him and your time is his. So you've got to ration your leisure time. Of course you are perfectly entitled to have times of fellowship and relaxation and friendship, but the devil will stir people up to do nothing else. As a Christian you’ve got to have this as a motto text very often: ‘I cannot come down. Why should the work cease while I leave it and come down to you?’ Maybe you haven't prepared your Sunday School class or some other vital thing for the Lord, and you’ve got to give it time and attention. Maybe you're being pressured out of time and energy for devotions, and for the more profitable things. Satan will find some amenable person, and he’ll make that person – maybe a good Christian – a snare to others by organising too many time-wasting things which take Christians away from their first objectives, and what they have given to the Lord. Your refusal can be very polite, but in your mind, you're saying, ‘I cannot do this. This is the Lord's time. I've had too much relaxation and leisure this week already, much more than any of the persecuted believers, much more than many other people committed to all kinds of responsibilities.’
