Think about this for more than a minute or two.
The following thoughts are taken from my class on Why do we pray?
Prayer is a task.
It is an art.
G-d doesn’t need prayer.
G-d doesn’t have needs.
We have needs.
G-d wants a relationship with us and this is why we pray.
Our prayer Grace after meals is a recognition of G-d’s involvement in the world. This doesn’t mean that G-d created the world and then said:” Bye you are on your own.”
Prayer means that G-d knows we have needs so tell me (G-d) about them.
Then you will know that (I) G-d am involved in the world.
G-d is involved in our day to day lives. G-d works these things out for us, so we have what we need. G-d is with us all the time, so prayer is making a philosophical statement that I know you are involved in my life to reinforce in my mind that you G-d are the one who provides for all my needs.
