Jeremiah 23:23-29
 
“Am I a God at hand, declares the Lord, and not a God far away? Can a man hide himself in secret places so that I cannot see him? declares the Lord. Do I not fill heaven and earth? declares the Lord. I have heard what the prophets have said who prophesy lies in my name, saying, ‘I have dreamed, I have dreamed!’ How long shall there be lies in the heart of the prophets who prophesy lies, and who prophesy the deceit of their own heart, who think to make my people forget my name by their dreams that they tell one another, even as their fathers forgot my name for Baal? Let the prophet who has a dream tell the dream, but let him who has my word speak my word faithfully. What has straw in common with wheat? declares the Lord. Is not my word like fire, declares the Lord, and like a hammer that breaks the rock in pieces?
 
Psalm 82

1 God has taken his place in the divine council;
    in the midst of the gods he holds judgment:
² “How long will you judge unjustly
    and show partiality to the wicked? Selah
³ Give justice to the weak and the fatherless;
    maintain the right of the afflicted and the destitute.
⁴ Rescue the weak and the needy;
    deliver them from the hand of the wicked.”
⁵ They have neither knowledge nor understanding,
    they walk about in darkness;
    all the foundations of the earth are shaken.
⁶ I said, “You are gods,
    sons of the Most High, all of you;
⁷ nevertheless, like men you shall die,
    and fall like any prince.”
⁸ Arise, O God, judge the earth;
    for you shall inherit all the nations!

Hebrew 12:1-14
 
Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God.
Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted. In your struggle against sin you have not yet resisted to the point of shedding your blood. And have you forgotten the exhortation that addresses you as sons?
“My son, do not regard lightly the discipline of the Lord,
    nor be weary when reproved by him.
For the Lord disciplines the one he loves,
    and chastises every son whom he receives.”
It is for discipline that you have to endure. God is treating you as sons. For what son is there whom his father does not discipline? If you are left without discipline, in which all have participated, then you are illegitimate children and not sons.Besides this, we have had earthly fathers who disciplined us and we respected them. Shall we not much more be subject to the Father of spirits and live? For they disciplined us for a short time as it seemed best to them, but he disciplines us for our good, that we may share his holiness. For the moment all discipline seems painful rather than pleasant, but later it yields the peaceful fruit of righteousness to those who have been trained by it.
Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. Strive for peace with everyone, and for the holiness without which no one will see the Lord.
 
Luke 12:49-56
 
“I came to cast fire on the earth, and would that it were already kindled! I have a baptism to be baptized with, and how great is my distress until it is accomplished!Do you think that I have come to give peace on earth? No, I tell you, but rather division. For from now on in one house there will be five divided, three against two and two against three. They will be divided, father against son and son against father, mother against daughter and daughter against mother, mother-in-law against her daughter-in-law and daughter-in-law against mother-in-law.”
He also said to the crowds, “When you see a cloud rising in the west, you say at once, ‘A shower is coming.’ And so it happens. And when you see the south wind blowing, you say, ‘There will be scorching heat,’ and it happens. You hypocrites! You know how to interpret the appearance of earth and sky, but why do you not know how to interpret the present time?
