GOD. God All Knowing? Why is Prayer or Worship still needed. GOD know it already before you pray?

Human being was created to be worship God. God deserved our worship for His Greatness and Kindness But a time is coming, and it is already here! Even now the true worshipers are being led by the Spirit to worship the Father according to the truth. These are the ones the Father is seeking to worship him John 4:23
