Ecclesiastes 2:4 says, I made me great works; I builded me houses; I planted me vineyards:  Solomon thought using his riches for his own benefit would bring him a sense of purpose.  He had first built a great Temple to God, but now he was building for himself.  We must be careful that we don't start building for God's glory and then get sidetracked to build only for ourselves.  Often today, people feel that if they can get a bigger, or better, house, or just more of them, it is going to bring happiness and purpose to life, but nothing is ever quite enough.  I am not sure how God feels about homes sitting empty for our occasional use while many people, even children, are homeless, but I cannot believe that He is pleased with His followers when we live this way.  If Solomon could not find purpose in building homes for himself, we should realize that we have little hope of doing it.  Verse five says, I made me gardens and orchards, and I planted trees in them of all kind of fruits:  In verse four Solomon said he had planted vineyards and here he continues with gardens and orchards.  There is certainly nothing wrong with doing these things, but they are not going to bring us to the purpose of our existence.  I think Solomon actually had I others do these things for Him, and they likely didn't enjoy the majority of the fruit of their labor.  Solomon continues in verse six, I made me pools of water, to water therewith the wood that bringeth forth trees: Again, the works that Solomon was doing were good, but they were being done for the wrong reason.  We certainly need to do good works today, but if they are done for simply to bring satisfaction in life, ultimately we are going to find ourselves dissatisfied.  We may do good things for the environment, but if we are only doing it for purpose in life, ultimately we will be disappointed.  We will find like Solomon, that good works alone are never enough if they are done for selfish reasons.
