Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things. Love never fails;…

• Philippians 2:1-8
  Therefore if there is any encouragement in Christ, if there is any consolation of love, if there is any fellowship of the Spirit, if any affection and compassion, make my joy complete by being of the same mind, maintaining the same love, united in spirit, intent on one purpose. Do nothing from selfishness or empty conceit, but with humility of mind regard one another as more important than yourselves; do not merely look out for your own personal interests, but also for the interests of others. Have this attitude in yourselves which was also in Christ Jesus, who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men. 8 Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross.
• Galatians 2:20
  I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.
• John 13:12-17
  So when He had washed their feet, and taken His garments and reclined at the table again, He said to them, “Do you know what I have done to you? You call Me Teacher and Lord; and you are right, for so I am. If I then, the Lord and the Teacher, washed your feet, you also ought to wash one another’s feet. For I gave you an example that you also should do as I did to you. Truly, truly, I say to you, a slave is not greater than his master, nor is one who is sent greater than the one who sent him. If you know these things, you are blessed if you do them.
• 1 Peter 2:21-25
  For you have been called for this purpose, since Christ also suffered for you, leaving you an example for you to follow in His steps, WHO COMMITTED NO SIN, NOR WAS ANY DECEIT FOUND IN HIS MOUTH; and while being reviled, He did not revile in return; while suffering, He uttered no threats, but kept entrusting Himself to Him who judges righteously; 24 and He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds you were healed. For you were continually straying like sheep, but now you have returned to the Shepherd and Guardian of your souls.
• Galatians 5:25-26
  If we live by the Spirit, let us also walk by the Spirit. Let us not become boastful, challenging one another, envying one another.
• Ephesians 2:8-10
  For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them.
• Ephesians 4:1-6
  Therefore I, the prisoner of the Lord, implore you to walk in a manner worthy of the calling with which you have been called, with all humility and gentleness, with patience, showing tolerance for one another in love, being diligent to preserve the unity of the Spirit in the bond of peace. There is one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all.
• 1 John 2:5-6
  …but whoever keeps His word, in him the love of God has truly been perfected. By this we know that we are in Him: the one who says he abides in Him ought himself to walk in the same manner as He walked.
• Romans 15:5-6
  Now may the God who gives perseverance and encouragement grant you to be of the same mind with one another according to Christ Jesus, so that with one accord you may with one voice glorify the God and Father of our Lord Jesus Christ.
• Romans 12:1-21
  Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship. And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. For through the grace given to me I say to everyone among you not to think more highly of himself than he ought to think; but to think so as to have sound judgment, as God has allotted to each a measure of faith. For just as we have many members in one body and all the members do not have the same function, so we, who are many, are one body in Christ, and individually members one of another. Since we have gifts that differ according to the grace given to us, each of us is to exercise them accordingly: if prophecy, according to the proportion of his faith; if service, in his serving; or he who teaches, in his teaching; or he who exhorts, in his exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness. Let love be without hypocrisy. Abhor what is evil; cling to what is good. Be devoted to one another in brotherly love; give preference to one another in honor; not lagging behind in diligence, fervent in spirit, serving the Lord; rejoicing in hope, persevering in tribulation, devoted to prayer, contributing to the needs of the saints, practicing hospitality. Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice, and weep with those who weep. Be of the same mind toward one another; do not be haughty in mind, but associate with the lowly. Do not be wise in your own estimation. Never pay back evil for evil to anyone. Respect what is right in the sight of all men. If possible, so far as it depends on you, be at peace with all men. Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, “VENGEANCE IS MINE, I WILL REPAY,” says the Lord. “BUT IF YOUR ENEMY IS HUNGRY, FEED HIM, AND IF HE IS THIRSTY, GIVE HIM A DRINK; FOR IN SO DOING YOU WILL HEAP BURNING COALS ON HIS HEAD.” Do not be overcome by evil, but overcome evil with good.
