Read Psalms 25:4  In this verse, King David is asking the Lord to show him the right way to go.  When your dad is going on a trip, he uses a GPS or a map.  The GPS is a computer device that your dad puts up on the dash in front of him to show him which way to go.  It is like a video game where you are going through a maze looking for treasure or looking to shoot the bad guy.  A map is the same thing only on paper.  If you know where you are going, or if you have been there before, you just remember the right way to go.  If you are not sure of where you are going, or you have never been there before, it is a good idea to use a GPS or a map so you won't get lost.  That is the way it is in life.  We haven't been to tomorrow yet.  You haven't been a teenager yet.  You haven't been a grown-up or you haven't been married or worked a job or many other things.  We don't know about the future, but Someone does.  Who knows what is going to happen tomorrow?  David is asking God to show him the way or the path.  Since there are many different ways to go in life, we need to know the best way so that we will be happy.  The best person to show us the right path in life is God because He knows exactly the best way that will make us happy.  God's way is always best!
