5 “And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full. 6 But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.”
9 “So I say to you: Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 10 For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened. 11 "Which of you fathers, if your son asks for a fish, will give him a snake instead? 12 Or if he asks for an egg, will give him a scorpion? 13 If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!”
The prayer of a righteous man is powerful and effective.
22 “Have faith in God,” Jesus answered. 23 “I tell you the truth, if anyone says to this mountain, ‘Go, throw yourself into the sea,’ and does not doubt in his heart but believes that what he says will happen, it will be done for him. 24 Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours. 25 And when you stand praying, if you hold anything against anyone, forgive him, so that your Father in heaven may forgive you your sins.”
6 Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. 7 And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
2 “This is what the LORD says, he who made the earth, the LORD who formed it and established it--the LORD is his name: 3 ‘Call to me and I will answer you and tell you great and unsearchable things you do not know.’”
“Prayer is always the preface to blessing. It goes before the blessing as the blessing’s shadow. When the sunlight of God’s mercies rises upon our necessities, it casts the shadow of prayer far down upon the plain. Prayer is thus connected with the blessing to show us the value of it. If we had the blessings without asking for them, we should think them common things; but prayer makes our mercies more precious than diamonds.” Charles H. Spurgeon
“There comes a time, in spite of our soft, modern ways, when we must be desperate in prayer, when we must wrestle, when we must be outspoken, shameless and importunate. Many of the prayers recorded in Scripture are ‘cries,’ and the Hebrew and Greek words are very strong. Despite opinions to the contrary, the Bible recognizes such a thing as storming heaven- ‘praying through.’ The fervent prayer of a righteous man is mighty in its working.” Cameron Thompson
“Men may spurn our appeals, reject our message, oppose our arguments, despise our persons; but they are helpless against our prayers.” J. Sidlow Baxter
“The one concern of the devil is to keep Christians from praying. He fears nothing from prayerless studies, prayerless work, and prayerless religion. He laughs at our toil, mocks at our wisdom, but trembles when we pray.” Samuel Chadwick
“Philippians 4:6 instructs us to pray about everything. If Paul had wanted us to limit our praying to everything big, he certainly would have told us. God is as interested in your small, seemingly insignificant requests as he is your kingdom-level, life changing needs. God’s interest in your prayers isn’t dependent upon their relative kingdom weightiness. Its’ based on his love for and interest in you.” Anonymous
“‘Dost thou want nothing, O poor soul? Hast thou nothing to ask? Oh yes! You say, a great deal. Well then, draw near to thy gracious King and Bridegroom without fear. Lo! He holds out His golden scepter to thee, saying, ‘Only ask: not the half, but the whole of My kingdom shall be granted; nay, I will give myself unto thee!’ O dear soul, pray, and tell Him everything that is wanting, be it ever so great or ever so small. His loving-kindness will hear even the least petition; nay, He will seem to be ignorant of what thou dost not tell Him. But whatever is poured out before Him is actually addressed and lodged in its proper place, and does not lie upon thy heart any longer, but upon His heart, which cannot rest till you are relieved. And if you have experienced His help aforetime in great or small things, you may depend on His readiness to help you out of troubles hereafter; only be earnest in prayer for His help. We often imagine we were willing and drawing near to Him, but He was unwilling, and refused our request; but it is not so: He rather draws us, and desires our relief more than we do; for it is He that works even this willing mind.” K.H. Von Bogatzky
“Do not think that your prayer, however weak or trembling, will be unregarded. Our God not only hears prayer but also loves to hear it. ‘He does not ignore the cry of the afflicted.’ True, He does take into consideration haughty looks and lofty words; He doesn’t care for the pomp and pageantry of kings; He doesn’t listen to the swell of martial music; He doesn’t regard the triumph and pride of man; but wherever there is a heart big with sorrow, or a lip quivering with agony, or a deep groan, or a penitential sigh, the heart of Jehovah is open; He marks it down in the registry of His memory; He puts our prayers, like rose leaves, between the pages of His book of remembrance, and when the volume is opened at last, a precious fragrance will release itself from it.” Charles H. Spurgeon
“The great tragedy of life is not unanswered prayer but unoffered prayer.” F. B. Meyer
