So I am glad I have been washed.

11And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.

Also:

Matthew 7
Judging Others
1"Do not judge, or you too will be judged. 2For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.

3"Why do you look at the speck of sawdust in your brother's eye and pay no attention to the plank in your own eye? 4How can you say to your brother, 'Let me take the speck out of your eye,' when all the time there is a plank in your own eye? 5You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye.

Another thing:

1My brothers, as believers in our glorious Lord Jesus Christ, don't show favoritism. 2Suppose a man comes into your meeting wearing a gold ring and fine clothes, and a poor man in shabby clothes also comes in. 3If you show special attention to the man wearing fine clothes and say, "Here's a good seat for you," but say to the poor man, "You stand there" or "Sit on the floor by my feet," 4have you not discriminated among yourselves and become judges with evil thoughts?

5Listen, my dear brothers: Has not God chosen those who are poor in the eyes of the world to be rich in faith and to inherit the kingdom he promised those who love him? 6But you have insulted the poor. Is it not the rich who are exploiting you? Are they not the ones who are dragging you into court? 7Are they not the ones who are slandering the noble name of him to whom you belong?

8If you really keep the royal law found in Scripture, "Love your neighbor as yourself,"[a] you are doing right. 9But if you show favoritism, you sin and are convicted by the law as lawbreakers. 10For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. 11For he who said, "Do not commit adultery,"[b] also said, "Do not murder."[c] If you do not commit adultery but do commit murder, you have become a lawbreaker.

12Speak and act as those who are going to be judged by the law that gives freedom, 13because judgment without mercy will be shown to anyone who has not been merciful. Mercy triumphs over judgment!

Last thing:

Romans 9

GOD'S SOVEREIGN CHOICE

1I speak the truth in Christ—I am not lying, my conscience confirms it in the Holy Spirit— 2I have great sorrow and unceasing anguish in my heart. 3For I could wish that I myself were cursed and cut off from Christ for the sake of my brothers, those of my own race, 4the people of Israel. Theirs is the adoption as sons; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. 5Theirs are the patriarchs, and from them is traced the human ancestry of Christ, who is God over all, forever praised![a] Amen.

6It is not as though God's word had failed. For not all who are descended from Israel are Israel. 7Nor because they are his descendants are they all Abraham's children. On the contrary, "It is through Isaac that your offspring will be reckoned."[b] 8In other words, it is not the natural children who are God's children, but it is the children of the promise who are regarded as Abraham's offspring. 9For this was how the promise was stated: "At the appointed time I will return, and Sarah will have a son."[c]

10Not only that, but Rebekah's children had one and the same father, our father Isaac. 11Yet, before the twins were born or had done anything good or bad—in order that God's purpose in election might stand: 12not by works but by him who calls—she was told, "The older will serve the younger."[d] 13Just as it is written: "Jacob I loved, but Esau I hated."[e]

14What then shall we say? Is God unjust? Not at all! 15For he says to Moses,
"I will have mercy on whom I have mercy,
and I will have compassion on whom I have compassion."[f] 16It does not, therefore, depend on man's desire or effort, but on God's mercy. 17For the Scripture says to Pharaoh: "I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth."[g] 18Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.

19One of you will say to me: "Then why does God still blame us? For who resists his will?" 20But who are you, O man, to talk back to God? "Shall what is formed say to him who formed it, 'Why did you make me like this?' "[h] 21Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?

22What if God, choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction? 23What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory— 24even us, whom he also called, not only from the Jews but also from the Gentiles? 25As he says in Hosea:
"I will call them 'my people' who are not my people;
and I will call her 'my loved one' who is not my loved one,"[i] 26and,
"It will happen that in the very place where it was said to them,
'You are not my people,'
they will be called 'sons of the living God.' "[j]

27Isaiah cries out concerning Israel:
"Though the number of the Israelites be like the sand by the sea,
only the remnant will be saved.
28For the Lord will carry out
his sentence on earth with speed and finality."[k]

29It is just as Isaiah said previously:
"Unless the Lord Almighty
had left us descendants,
we would have become like Sodom,
we would have been like Gomorrah."[l]
Israel's Unbelief
30What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; 31but Israel, who pursued a law of righteousness, has not attained it. 32Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the "stumbling stone." 33As it is written:
"See, I lay in Zion a stone that causes men to stumble
and a rock that makes them fall,
and the one who trusts in him will never be put to shame."[m]
