Then Abraham approached him and said: "Will you sweep away the righteous with the wicked? What if there are fifty righteous people in the city? Will you really sweep it away and not spare the place for the sake of the fifty righteous people in it? Far be it from you to do such a thing—to kill the righteous with the wicked, treating the righteous and the wicked alike. Far be it from you! Will not the Judge of all the earth do right?" The LORD said, "If I find fifty righteous people in the city of Sodom, I will spare the whole place for their sake." Then Abraham spoke up again: "Now that I have been so bold as to speak to the Lord, though I am nothing but dust and ashes, what if the number of the righteous is five less than fifty? Will you destroy the whole city because of five people?" "If I find forty-five there," he said, "I will not destroy it." Once again he spoke to him, "What if only forty are found there?" He said, "For the sake of forty, I will not do it." Then he said, "May the Lord not be angry, but let me speak. What if only thirty can be found there?" He answered, "I will not do it if I find thirty there." Abraham said, "Now that I have been so bold as to speak to the Lord, what if only twenty can be found there?" He said, "For the sake of twenty, I will not destroy it." Then he said, "May the Lord not be angry, but let me speak just once more. What if only ten can be found there?" He answered, "For the sake of ten, I will not destroy it."
2 Chronicles 7:14-15
If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. Now my eyes will be open and my ears attentive to the prayers offered in this place.es are upon you."
While Ezra was praying and confessing, weeping and throwing himself down before the house of God, a large crowd of Israelites—men, women and children—gathered around him. They too wept bitterly.
"Now therefore, O our God, the great, mighty and awesome God, who keeps his covenant of love, do not let all this hardship seem trifling in your eyes--the hardship that has come upon us, upon our kings and leaders, upon our priests and prophets, upon our fathers and all your people, from the days of the kings of Assyria until today.
So he said he would destroy them— had not Moses, his chosen one, stood in the breach before him to keep his wrath from destroying them.
He saw that there was no one, he was appalled that there was no one to intervene; so his own arm worked salvation for him, and his own righteousness sustained him.
I have posted watchmen on your walls, O Jerusalem; they will never be silent day or night. You who call on the LORD, give yourselves no rest and give him no rest till he establishes Jerusalem and makes her the praise of the earth.
I looked for a man among them who would build up the wall and stand before me in the gap on behalf of the land so I would not have to destroy it, but I found none.So I will pour out my wrath on them and consume them with my fiery anger, bringing down on their own heads all they have done, declares the Sovereign LORD.
Now when Daniel learned that the decree had been published, he went home to his upstairs room where the windows opened toward Jerusalem. Three times a day he got down on his knees and prayed, giving thanks to his God, just as he had done before.
Give glory to the LORD your God before he brings the darkness, before your feet stumble on the darkening hills. You hope for light, but he will turn it to thick darkness and change it to deep gloom.But if you do not listen, I will weep in secret because of your pride; my eyes will weep bitterly, overflowing with tears, because the LORD's flock will be taken captive.
Streams of tears flow from my eyes because my people are destroyed.My eyes will flow unceasingly, without relief, until the LORD looks down from heaven and sees.
Let the priests, who minister before the LORD, weep between the temple porch and the altar. Let them say, "Spare your people, O LORD. Do not make your inheritance an object of scorn, a byword among the nations. Why should they say among the peoples, 'Where is their God?'
But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers."
After Jesus said this, he looked toward heaven and prayed: "Father, the time has come. Glorify your Son, that your Son may glorify you. For you granted him authority over all people that he might give eternal life to all those you have given him. Now this is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent. I have brought you glory on earth by completing the work you gave me to do. And now, Father, glorify me in your presence with the glory I had with you before the world began. "I have revealed you to those whom you gave me out of the world. They were yours; you gave them to me and they have obeyed your word. Now they know that everything you have given me comes from you. For I gave them the words you gave me and they accepted them. They knew with certainty that I came from you, and they believed that you sent me. I pray for them. I am not praying for the world, but for those you have given me, for they are yours. All I have is yours, and all you have is mine. And glory has come to me through them. I will remain in the world no longer, but they are still in the world, and I am coming to you. Holy Father, protect them by the power of your name--the name you gave me--so that they may be one as we are one. While I was with them, I protected them and kept them safe by that name you gave me. None has been lost except the one doomed to destruction so that Scripture would be fulfilled. "I am coming to you now, but I say these things while I am still in the world, so that they may have the full measure of my joy within them. I have given them your word and the world has hated them, for they are not of the world any more than I am of the world. My prayer is not that you take them out of the world but that you protect them from the evil one. They are not of the world, even as I am not of it. Sanctify them by the truth; your word is truth. As you sent me into the world, I have sent them into the world. For them I sanctify myself, that they too may be truly sanctified. "My prayer is not for them alone. I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one: I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me. "Father, I want those you have given me to be with me where I am, and to see my glory, the glory you have given me because you loved me before the creation of the world. "Righteous Father, though the world does not know you, I know you, and they know that you have sent me. I have made you known to them, and will continue to make you known in order that the love you have for me may be in them and that I myself may be in them."
So Peter was kept in prison, but the church was earnestly praying to God for him. The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance. Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. "Quick, get up!" he said, and the chains fell off Peter's wrists. Then the angel said to him, "Put on your clothes and sandals." And Peter did so. "Wrap your cloak around you and follow me," the angel told him. Peter followed him out of the prison, but he had no idea that what the angel was doing was really happening; he thought he was seeing a vision. They passed the first and second guards and came to the iron gate leading to the city. It opened for them by itself, and they went through it. When they had walked the length of one street, suddenly the angel left him. Then Peter came to himself and said, "Now I know without a doubt that the Lord sent his angel and rescued me from Herod's clutches and from everything the Jewish people were anticipating." When this had dawned on him, he went to the house of Mary the mother of John, also called Mark, where many people had gathered and were praying.
In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express
1 Timothy 2:1-4
I urge, then, first of all, that requests, prayers, intercession and thanksgiving be made for everyone— for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness. This is good, and pleases God our Savior, who wants all men to be saved and to come to a knowledge of the truth.
During the days of Jesus' life on earth, he offered up prayers and petitions with loud cries and tears to the one who could save him from death, and he was heard because of his reverent submission.
Now there have been many of those priests, since death prevented them from continuing in office; but because Jesus lives forever, he has a permanent priesthood. Therefore he is able to save completel those who come to God through him, because he always lives to intercede for them.
Is any one of you in trouble? He should pray. Is anyone happy? Let him sing songs of praise. Is any one of you sick? He should call the elders of the church to pray over him and anoint him with oil in the name of the Lord. And the prayer offered in faith will make the sick person well; the Lord will raise him up. If he has sinned, he will be forgiven. Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective.
