Psa 28:1 To you I call, O LORD my Rock; do not turn a deaf ear to me. For if you remain silent, I will be like those who have gone down to the pit."

Do you ever think that we spend a lot of time thinking about how we are acting and much how we need to fear God. But do you consider that God created us for Him and not our performing for Him? This is God's world that is a history of God's performance. After all God does not need us to add to His stamp on the history of redemption. So we learn from the Psalmist that we would be much more secure and cheerful if we stopped taking the glory in thinking that our history was significant. We are to magnify and praise God for His works. 

Did you ever consider that most of the celebrating of the OT church centered around Isreal deliverance from Ejypt? If you think about it God had to do a work that was impossible humanly speaking. He had to take 100s of thousands of people across a dangerous land with no supplies and no way of sustaining their lives. In moving from one place to another they had no time to farm or attend to the sickness of the people. You see God not only had to do all the work but He had it written down for our learning so that He would encourage us who live with all of our needs being met to depend upon Him.

God teaching is centered around this extreme example of making His people totally dependent on Him for everything. This is why we find the focus of the Psalmist is on our speech so that we will learn to focus on God's works and not us.
