Why Do We Pray?
Prayer is talking with God. When we have a good friend, we talk to that person about all sorts of things. By spending time with that person we build a relationship and become friends.
In the same way, we should talk to God about what is happening in our life. God wants us to share our life with Him, to tell Him about what makes us happy, sad, and afraid. He wants to know what we want and what we would like Him to do, for ourself and for others. Also, when we pray, we open ourself up to God so that He can make good and positive changes in us.
