"And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Do not be like them, for your Father knows what you need before you ask him."
Two phrases pop out at me: "empty phrases" and "many words". Several times a week I pray the Lord's prayer (which directly follows these verses) in a group setting and I have to consciously slow my self down as I pray so that I can think about the words that I am praying. It is so easy to pray and not think about the words that you are praying.
Jesus helps us by telling us that it is not really about the great words that we speak but simply that we speak to the Father. He seems to be saying that the idea of prayer is not really the effective communication of our prayers but simply the actual act of prayer. He tells us that God already knows what we need and indicates that God is waiting for us to simply pray.. to simply invite Him to help us.. to simply share our hearts with our Father.
Lord help me to be real when I pray.
