(Luke 18:1-8 NIV) 1 Then Jesus told his disciples a parable to show them that they should always pray and not give up. 2 He said: “In a certain town there was a judge who neither feared God nor cared what people thought. 3 And there was a widow in that town who kept coming to him with the plea, ‘Grant me justice against my adversary.’ 4 “For some time he refused. But finally he said to himself, ‘Even though I don’t fear God or care what people think, 5 yet because this widow keeps bothering me, I will see that she gets justice, so that she won’t eventually come and attack me!’” 6 And the Lord said, “Listen to what the unjust judge says. 7 And will not God bring about justice for his chosen ones, who cry out to him day and night? Will he keep putting them off? 8 I tell you, he will see that they get justice, and quickly. However, when the Son of Man comes, will he find faith on the earth?”

(1 Peter 5:8 KJV) Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:

(Ephesians 6:10-12 MSG) And that about wraps it up. God is strong, and he wants you strong. So take everything the Master has set out for you, well-made weapons of the best materials. And put them to use so you will be able to stand up to everything the Devil throws your way. This is no weekend war that we’ll walk away from and forget about in a couple of hours. This is for keeps, a life-or-death fight to the finish against the Devil and all his angels.

(Romans 12:19 KJV) Vengeance is mine; I will repay, saith the Lord.

(James 5:16 KJV) Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
