"...The earnest (heartfelt, continued) prayer of a righteous man makes tremendous power available—dynamic in its working" (James 5:16 AMP).

Prayer is fellowshipping with the Father—a vital, personal contact with God Who is more than enough. We are to be in constant communion with Him:
For the eyes of the Lord are upon the righteous—those who are upright and in right standing with God—and His ears are attentive (open) to their prayer....
(1 Peter 3:12 AMP)
Prayer is not to be a religious form with no power. It is to be effective and accurate and bring results. God watches over His Word to perform it (Jer. 1:12).

Prayer that brings results must be based on God's Word.
For the Word that God speaks is alive and full of power—making it active, operative, energizing and effective; it is sharper than any two-edged sword, penetrating to the dividing line of the breath of life (soul) and [the immortal] spirit, and of joints and marrow [that is, of the deepest parts of our nature] exposing and sifting and analyzing and judging the very thoughts and purposes of the heart.
(Heb. 4:12 AMP)
Prayer is this "living" Word in our mouths. Our mouths must speak forth faith, for faith is what pleases God. (Heb. 11:6) We hold His Word up to Him in prayer, and our Father sees Himself in His Word.

God's Word is our contact with Him. We put Him in remembrance of His Word (Isa. 43:26), placing a demand on His ability in the name of our Lord Jesus. We remind Him that He supplies all of our needs according to His riches in glory by Christ Jesus (Phil. 4:19). That Word does not return to Him void—without producing any effect, useless—but it shall accomplish that which He pleases and purposes, and it shall prosper in the thing for which He sent it (Isa. 55:11). Hallelujah!

God did not leave us without His thoughts and His ways for we have His Word—His bond. God instructs us to call Him, and He will answer and show us great and mighty things (Jer. 33:3). Prayer is to be exciting—not drudgery.

It takes someone to pray. God moves as we pray in faith—believing. He says that His eyes run to and fro throughout the whole earth to show Himself strong in behalf of those whose hearts are blameless toward Him (2 Chron. 16:9).

We are blameless. (Eph. 1:4.) We are His very own children (Eph. 1:5). We are His righteousness in Christ Jesus (2 Cor. 5:21). He tells us to come boldly to the throne of grace and obtain mercy and find grace to help in time of need—appropriate and well-timed help (Heb. 4:16). Praise the Lord!
