God answers prayer not because you are righteous.

So I said: "Woe is me, for I am undone! Because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts." 

Isaiah 6:5

Why does God answer prayer? Let's not imagine that it's because somebody was good. We Protestants think we don't believe in saints, but we do. We canonize them: we have Saint George Mueller, Saint C.H. Spurgeon, Saint D.L. Moody and Saint A.B. Simpson. We get the idea that God answered prayer for them because they were really good. They would deny that fervently if they were here.

Nobody ever got anything from God on the grounds that he deserved it. Having fallen, man deserves only punishment and death. So if God answers prayer, it's because God is good. From His goodness, His lovingkindness, His good-natured benevolence, God does it! That's the source of everything. The Attributes of God, pp. 46-47

but...

what about James 5:16?  "The effectual fervent prayer of a righteous man availeth much."  Yes, it's true.  The prayer of a righteous man is powerful and effective, but who is the righteous man?  It is the one justified by the righteousness of Christ.

"As it is written:  None is righteous, no, not one." (Romans 3:10)

"But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— the righteousness of God through faith in Jesus Christ for all who believe." (Romans 3:21)

"For if Abraham was justified by works, he has something to boast about, but not before God. For what does the Scripture say? 'Abraham believed God, and it was counted to him as righteousness.' Now to the one who works, his wages are not counted as a gift but as his due. And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness." (Romans 4:2-5)

"For Christ is the end of the law for righteousness to everyone who believes. For Moses writes about the righteousness that is based on the law, that the person who does the commandments shall live by them. But the righteousness based on faith says, 'Do not say in your heart, 'Who will ascend into heaven?' (that is, to bring Christ down) or 'Who will descend into the abyss?' (that is, to bring Christ up from the dead). But what does it say? 'The word is near you, in your mouth and in your heart' (that is, the word of faith that we proclaim); because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved." (Romans 10:4-9)

 "For our sake He made Him to be sin who knew no sin, so that in Him we might become the righteousness of God." (2 Corinthians 5:21)

"I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. I do not nullify the grace of God, for if righteousness were through the law, then Christ died for no purpose." (Galatians 2:20-21)

"And it is my prayer that your love may abound more and more, with knowledge and all discernment, so that you may approve what is excellent, and so be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ, to the glory and praise of God." (Philippians 1:9-11)

"Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith" (Philippians 3:8-9)

Thank You, God, that You are indeed good,

You are faithful,

You are gracious,

You are full of lovingkindness and benevolence.

Thank You that You do in fact answer prayer!

Amen.
