Dan 6:10-11, 19-28 Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime. 11 Then these men assembled, and found Daniel praying and making supplication before his God. . . . 19 Then the king arose very early in the morning, and went in haste unto the den of lions. 20 And when he came to the den, he cried with a lamentable voice unto Daniel: and the king spake and said to Daniel, O Daniel, servant of the living God, is thy God, whom thou servest continually, able to deliver thee from the lions? 21 Then said Daniel unto the king, O king, live for ever. 22 My God hath sent his angel, and hath shut the lions' mouths, that they have not hurt me: forasmuch as before him innocency was found in me; and also before thee, O king, have I done no hurt. 23 Then was the king exceeding glad for him, and commanded that they should take Daniel up out of the den. So Daniel was taken up out of the den, and no manner of hurt was found upon him, because he believed in his God. 24 And the king commanded, and they brought those men which had accused Daniel, and they cast them into the den of lions, them, their children, and their wives; and the lions had the mastery of them, and brake all their bones in pieces or ever they came at the bottom of the den. 25 Then king Darius wrote unto all people, nations, and languages, that dwell in all the earth; Peace be multiplied unto you. 26 I make a decree, That in every dominion of my kingdom men tremble and fear before the God of Daniel: for he is the living God, and stedfast for ever, and his kingdom that which shall not be destroyed, and his dominion shall be even unto the end. 27 He delivereth and rescueth, and he worketh signs and wonders in heaven and in earth, who hath delivered Daniel from the power of the lions. 28 So this Daniel prospered in the reign of Darius, and in the reign of Cyrus the Persian.

Luke 21:36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.

John 9:31 Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth.

Ps 66:18 If I regard iniquity in my heart, the Lord will not hear me:

Job 27:8-10 For what is the hope of the hypocrite, though he hath gained, when God taketh away his soul? 9 Will God hear his cry when trouble cometh upon him? 10 Will he delight himself in the Almighty? will he always call upon God?

Job 35:13 Surely God will not hear vanity, neither will the Almighty regard it.

Isa 59:2-8 But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear. 3 For your hands are defiled with blood, and your fingers with iniquity; your lips have spoken lies, your tongue hath muttered perverseness. 4 None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity. 5 They hatch cockatrice' eggs, and weave the spider's web: he that eateth of their eggs dieth, and that which is crushed breaketh out into a viper. 6 Their webs shall not become garments, neither shall they cover themselves with their works: their works are works of iniquity, and the act of violence is in their hands. 7 Their feet run to evil, and they make haste to shed innocent blood: their thoughts are thoughts of iniquity; wasting and destruction are in their paths. 8 The way of peace they know not; and there is no judgment in their goings: they have made them crooked paths: whosoever goeth therein shall not know peace.

Heb 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

James 1:6-8 But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. 7 For let not that man think that he shall receive any thing of the Lord. 8 A double minded man is unstable in all his ways.

Prov 28:9 He that turneth away his ear from hearing the law, even his prayer shall be abomination.

Jer 14:10-12 Thus saith the LORD unto this people, Thus have they loved to wander, they have not refrained their feet, therefore the LORD doth not accept them; he will now remember their iniquity, and visit their sins. 11 Then said the LORD unto me, Pray not for this people for their good. 12 When they fast, I will not hear their cry; and when they offer burnt offering and an oblation, I will not accept them: but I will consume them by the sword, and by the famine, and by the pestilence.

1 Pet 3:7 Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.

Ps 106:13-15 They soon forgat his works; they waited not for his counsel: 14 But lusted exceedingly in the wilderness, and tempted God in the desert. 15 And he gave them their request; but sent leanness into their soul.

Matt 26:39 And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.

2 Cor 12:7-10 And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. 8 For this thing I besought the Lord thrice, that it might depart from me. 9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. 10 Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.

Lam 3:25-28 The LORD is good unto them that wait for him, to the soul that seeketh him. 26 It is good that a man should both hope and quietly wait for the salvation of the LORD. 27 It is good for a man that he bear the yoke in his youth. 28 He sitteth alone and keepeth silence, because he hath borne it upon him.
