Jesus died to create unity in all of His people spanning across socioeconomic status, age, and ethnicity (Ephesians 2). Anything less is not in accordance with the will of God. Biblical unity is not uniformity. Unity amongst diversity is intended to be a marker of the church and its local and global context.
"So God created mankind in his own image, in the image of God he created them; male and female he created them."
“The community is to have the same rules for you and for the foreigner residing among you; this is a lasting ordinance for the generations to come. You and the foreigner shall be the same before the LORD.”
"For the Lord your God is God of gods and Lord of lords, the great God, mighty and awesome, who shows no partiality and accepts no bribes. He defends the cause of the fatherless and the widow, and loves the foreigner residing among you, giving them food and clothing. And you are to love those who are foreigners, for you yourselves were foreigners in Egypt."
"Have we not all one Father? Has not one God created us? Why then are we faithless to one another, profaning the covenant of our fathers?"
"Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
"I do not ask for these only, but also for those who will believe in me through their word, that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me"
"Then Peter began to speak: “I now realize how true it is that God does not show favoritism but accepts from every nation the one who fears him and does what is right."
"May the God of endurance and encouragement grant you to live in such harmony with one another, in accord with Christ Jesus, that together you may with one voice glorify the God and Father of our Lord Jesus Christ."
"I appeal to you, brothers, by the name of our Lord Jesus Christ, that all of of you agree, and that there be no divisions among you, but that you be united in the same mind and the same judgment."
"For we were all baptized by one Spirit so as to form one body—whether Jews or Gentiles, slave or free—and we were all given the one Spirit to drink."
"For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility."
"For through him we both have access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit."
"So if there is any encouragement in Christ, any comfort from love, any participation in the Spirit, any affection and sympathy, complete my joy by being of the same mind, having the same love, being in full accord and of one mind. Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others."
"We love because he first loved us. If anyone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen. And this commandment we have from him: whoever loves God must also love his brother."
"And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth."
"After this I looked, and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and before the Lamb. They were wearing white robes and were holding palm branches in their hands."
