And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him. Elias was a man subject to like passions as we are, and he prayed earnestly that it might not rain: and it rained not on the earth by the space of three years and six months. And he prayed again, and the heaven gave rain, and the earth brought forth her fruit.
Effective prayers are based on the Word of God.
God’s Word is the source of prayer. When you pray the Word, heaven and earth will move to bring it to pass.
Prayer is all about advancing the will of heaven in the earth.
Call on heaven to affect earth.
For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord . For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts. For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
Everything that God said in His Word will happen.
When was the last time you returned God’s Word to Him?
If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you. Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?
My covenant will I not break, nor alter the thing that is gone out of my lips.
And Joshua adjured them at that time, saying, Cursed be the man before the Lord , that riseth up and buildeth this city Jericho: he shall lay the foundation thereof in his firstborn, and in his youngest son shall he set up the gates of it.
1 Kings 16:29-34
And in the thirty and eighth year of Asa king of Judah began Ahab the son of Omri to reign over Israel: and Ahab the son of Omri reigned over Israel in Samaria twenty and two years. And Ahab the son of Omri did evil in the sight of the Lord above all that were before him.  And it came to pass, as if it had been a light thing for him to walk in the sins of Jeroboam the son of Nebat, that he took to wife Jezebel the daughter of Ethbaal king of the Zidonians, and went and served Baal, and worshipped him. And he reared up an altar for Baal in the house of Baal, which he had built in Samaria. And Ahab made a grove; and Ahab did more to provoke the Lord God of Israel to anger than all the kings of Israel that were before him. In his days did Hiel the Beth-elite build Jericho: he laid the foundation thereof in Abiram his firstborn, and set up the gates thereof in his youngest son Segub, according to the word of the Lord , which he spake by Joshua the son of Nun.
1 Kings 17:1
And Elijah the Tishbite, who was of the inhabitants of Gilead, said unto Ahab, As the Lord God of Israel liveth, before whom I stand, there shall not be dew nor rain these years, but according to my word.
Deuteronomy 10:8, 11:16
There are two guarantees in prayer:
The Word of God
The name of Jesus.
God always has what He says.
When you are standing in faith on a promise you found in God’s Word, know that it will come to pass.
In any situation, all we need is a promise from God’s Word to stand on. When we declare it, we will see it come to pass.
I will worship toward thy holy temple, and praise thy name for thy lovingkindness and for thy truth: for thou hast magnified thy word above all thy name.
God’s Word makes His name.
And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask any thing in my name, I will do it.
2 Chronicles 20:5-9
And Jehoshaphat stood in the congregation of Judah and Jerusalem, in the house of the Lord , before the new court, And said, O Lord God of our fathers, art not thou God in heaven? and rulest not thou over all the kingdoms of the heathen? and in thine hand is there not power and might, so that none is able to withstand thee? Art not thou our God, who didst drive out the inhabitants of this land before thy people Israel, and gavest it to the seed of Abraham thy friend for ever? And they dwelt therein, and have built thee a sanctuary therein for thy name, saying, If, when evil cometh upon us, as the sword, judgment, or pestilence, or famine, we stand before this house, and in thy presence, (for thy name is in this house,) and cry unto thee in our affliction, then thou wilt hear and help.
God honors faith and He honors His Word.
2 Chronicles 20:20-23
And they rose early in the morning, and went forth into the wilderness of Tekoa: and as they went forth, Jehoshaphat stood and said, Hear me, O Judah, and ye inhabitants of Jerusalem; Believe in the Lord your God, so shall ye be established; believe his prophets, so shall ye prosper. And when he had consulted with the people, he appointed singers unto the Lord , and that should praise the beauty of holiness, as they went out before the army, and to say, Praise the Lord ; for his mercy endureth for ever. And when they began to sing and to praise, the Lord set ambushments against the children of Ammon, Moab, and mount Seir, which were come against Judah; and they were smitten. For the children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy them : and when they had made an end of the inhabitants of Seir, every one helped to destroy another.
When you praise God, you confuse the enemy. And the enemy will never join in your praise.
