Why is it important to pray if God knows everything?

Though God is omniscient and knows our needs before we ask, prayer is integral in the believer's life because God has ordained it as the means to fulfill His purposes. This idea is supported in Ezekiel 36, where it indicates that the Lord would be enquired of by His people to act on their behalf. Thus, prayer serves not only as a way to express our needs and desires to God, but also as a means of experiencing relationship and communion with Him, thereby allowing us to acknowledge His sovereignty and actively engage in His work on earth.
