Praying for the Fulfillment of Prophecy

In Scripture, where can we see the necessity of praying for the fulfillment of prophecy? In the Babylonian Captivity, Daniel interceded for Israel to be allowed to return after 70 years (Daniel 9:2-3), just as promised by Jehovah (Jeremiah 29:10). If prophecy will be fulfilled because God promised it, why do we still need to pray? “I the LORD have spoken it, and I will do it. Thus saith the Lord GOD; I will yet for this be enquired of by the house of Israel, to do it for them” (Ezekiel 36:36-37 KJV). In spiritual warfare, prayer is commanded, but it most importantly draws us to God, as well as extends His supernatural influence in this world. May Thy kingdom come, and Thy will be done on earth, as it is in heaven. Amen.
