Don't just pretend to love others. Really love them. Hate what is wrong. Hold tightly to what is good. Let love be without hypocrisy. Abhor what is evil; cling to what is good.
Romans 12:9

Most important of all, continue to show deep love for each other, for love covers a multitude of sins. Show hospitality to one another without grumbling.
1 Peter 4:8-9

Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart.
1 Peter 1:22

A new commandment I give you: Love one another. As I have loved you, so also you must love one another.
John 13:34


For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins.


17 “And now, brothers, I know that you acted in ignorance, as did also your rulers. 18 But what God foretold by the mouth of all the prophets, that his Christ would suffer, he thus fulfilled. 19 Repent therefore, and turn back, that your sins may be blotted out, 20 that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, 21 whom heaven must receive until the time for restoring all the things about which God spoke by the mouth of his holy prophets long ago. 22 Moses said, ‘The Lord God will raise up for you a prophet like me from your brothers. You shall listen to him in whatever he tells you. 23 And it shall be that every soul who does not listen to that prophet shall be destroyed from the people.’ 24 And all the prophets who have spoken, from Samuel and those who came after him, also proclaimed these days. 25 You are the sons of the prophets and of the covenant that God made with your fathers, saying to Abraham, ‘And in your offspring shall all the families of the earth be blessed.’ 26 God, having raised up his servant, sent him to you first, to bless you by turning every one of you from your wickedness.”
Acts 3:17-26

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

“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? 4 How 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? You 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. For God will judge you in the same way you judge others, and he will apply to you the same rules you apply to others.

Don't speak evil against each other, dear brothers and sisters. If you criticize and judge each other, then you are criticizing and judging God's law.
Mat 7:1-5


God’s Righteous Judgment
1You, therefore, have no excuse, you who pass judgment on someone else, for at whatever point you judge another, you are condemning yourself, because you who pass judgment do the same things. 2Now we know that God’s judgment against those who do such things is based on truth. 3So when you, a mere human being, pass judgment on them and yet do the same things, do you think you will escape God’s judgment? 4Or do you show contempt for the riches of his kindness, forbearance and patience, not realizing that God’s kindness is intended to lead you to repentance?

5But because of your stubbornness and your unrepentant heart, you are storing up wrath against yourself for the day of God’s wrath, when his righteous judgment will be revealed. 6God “will repay each person according to what they have done.” a 7To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life. 8But for those who are self-seeking and who reject the truth and follow evil, there will be wrath and anger. 9There will be trouble and distress for every human being who does evil: first for the Jew, then for the Gentile; 10but glory, honor and peace for everyone who does good: first for the Jew, then for the Gentile. 11For God does not show favoritism.

12All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law. 13For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous. 14(Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law. 15They show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts sometimes accusing them and at other times even defending them.) 16This will take place on the day when God judges people’s secrets through Jesus Christ, as my gospel declares.
Romans 2:1-29


And he said to him, all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets.
Mark 12:30-31

Do to others as you would have them do to you.
Luke 6:31

Do everything in love.
1 Cor 16:4
