Effective, fervent prayer is simply, learning to agree with God. Understanding what God's Will is and merely saying, Amen. You may say, how could I possibly know what God's Will is? God's Own Word, that is His Will. Search His Word, then agree with Him. The following is an example taken from Psalm 91.

Father I praise You that I dwell in the secret place of the Most High and that I remain stable and fixed under the shadow of the Almighty, whose power no foe can withstand. I will say of you Lord, "The Lord is my refuge and my fortress, my God; on Him I lean and rely, and in Him I confidently trust!" For then You will deliver me from the snare of the fowler and from the deadly pestilence. Then You will cover me with Your pinions, and under Your wings shall I trust and find refuge. Your truth and Your faithfulness are a shield and buckler. I shall not be afraid of the terror of the night, nor of the evil plots and slanders of the wicked that flies by day, nor of the pestilence that stalks in darkness, not of the destruction and sudden death that surprise and lay waste at noonday.

A thousand may fall at my side, and ten thousand at my right hand, but it shall not come near me. Only a spectator shall I be, inaccessible in the secret place of the Most High, as I witness the reward of the wicked. Because I have made You, Lord, my refuge, and the Most High my dwelling place, there shall no evil befall me, nor any plague or calamity come near my tent. For You give Your angels especial charge over me, to accompany and defend and preserve me in all my ways of obedience and service. Your angels shall bear me up on their hands, lest I dash my foot against a stone. I shall tread upon the lion and adder; the young lion and the serpent shall I trample underfoot. Because I have set my love upon You, therefore will You deliver me. You will set me on high, because I know and understand Your Name.

I have a personal knowledge of Your mercy, love, and kindness. I trust and rely on You, knowing You will never forsake me, no, never. I shall call upon You, and You will answer me. You will be with me in trouble. You will deliver me and honor me. With long life will You satisfy me and show me Your Salvation!

The Psalmist has learned to come into agreement with the Most High God regarding his own life and his circumstances. The one offering this prayer has received a revelation that the key is... agreeing with God. The Lord has made great and marvelous promises regarding His Love for you and His Provision for all of your needs. These Promises are found in His Word. I encourage you to get into your Bible, ask the Lord to show you His desire for you. Once He does, begin confessing it and come into agreement with God Himself concerning your needs and the desires of your heart. That is The Prayer of Agreement.
