The prayer of the righteous is powerful and effective

Quotes from the bible NIV

"The Lord detests the sacrifice of the wicked, but the prayer of the upright pleases him" - Pr 15:8.

"The Lord is far from the wicked but he hears the prayer of the righteous" - Pr 15:29

"For the eyes of the Lord are on the righteous and his ears are attentive to their prayer, but the face of the Lord is against those who do evil" - 1 Pet 3:12

"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" - Jas 5:16

"This is the confidence we have in approaching God: that if ask anything according to his will, he hears us. And if we know that he hears us - whatever we ask - we know that we have what we asked of him." - 1 Jn 5:14-15

"Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything that we ask, because we obey his commands and do what pleases him." 1 Jn 3:21-22

In studying these verses, it would be important that our relationship with God is right, that our heart is right with God so God will hear our prayers. So often in my experience, when I am walking in the light, it is easy to pray but when I have sin and walking in the darkness, my approach to praying for others is that I feel uneasy praying.

The prayer of the righteous is powerful and effective, if we want our prayers to be heard by God and receive in what we ask according to his will, then we should be right with God that we obey his commands and do what pleases him.

Of course if we are not right with God, or have sin against him, we should confess and pray for his forgiveness so that our hearts may be right with God.
