Ecclesiastes 4:7 says, Then I returned, and I saw vanity under the sun.  Solomon was still looking for something to give him purpose, and nothing in this world was providing it.  As people look for meaning today, outside the will of God, they are going to be just as disappointed.  Verse eight says, There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.  I believe Solomon was saying that a person who lives by himself and has no children may really question why they are working so hard.  It is not that they don't want to share their blessings in this case, but there is no no one to share them with, and this can cause a feeling of despair.  Still, they could share with others less fortunate and receive a blessing from it.  Verse nine says, Two are better than one; because they have a good reward for their labour.  Man was not intended to live alone.  From creation, men and women were designed to be together, to get married and bring completion to one another.  They see the good reward for their labor as the share in it.  Verse ten says, For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up.  We have seen the commercial that says, Help, I have fallen and can't get up.  This applies to being out working alone as well.  If we are in an accident, we may not be able to get up, but if someone is with us, they can help.  I think this applies to emotionally as well .  If we are down, then we have someone to lift us up.  Verse eleven says, Again, if two lie together, then they have heat: but how can one be warm alone?  Now we might just say turn up the heat or turn up the blanket, but they did not have that advantage, and neither do a lot of people in the world today.  They need each other to just stay warm.  Verse twelve says, And if one prevail against him, two shall withstand him; and a threefold cord is not quickly broken.  Just having one stand with us in the adversities of life make us much stronger than standing alone.
