you're coming near to the end of your shift  you're not waking up because it's getting near morning whereas everybody else is, you're finding it much more difficult to carry on because you've gone through the whole night working, the night is well along and it becomes increasingly more difficult to stay awake so physically, spiritually, whatever way you look at it, it is certainly very difficult to stay awake in the truth today, but it isn't that difficult and it isn't er a hurdle that none of us can overcome, jehovah says that his load is light, jesus echoed that didn't he and it is true that if we do jehovah's  will, jehovah's way, then it will be made light for us, he will help us to stay awake, but he's not going to allow us to slumber and drift off into obscurity, but it all comes back in hinges upon us and that's why the counsel is in verse thirteen  as a day, as in a day time look, let us walk decently  so we have to do something don't we?
