Marks of the True Christian
[9] Let love be genuine. Abhor what is evil; hold fast to what is good. [10] Love one another with brotherly affection. Outdo one another in showing honor. [11] Do not be slothful in zeal, be fervent in spirit,(1) serve the Lord. [12] Rejoice in hope, be patient in tribulation, be constant in prayer. [13] Contribute to the needs of the saints and seek to show hospitality.
[14] Bless those who persecute you; bless and do not curse them. [15] Rejoice with those who rejoice, weep with those who weep. [16] Live in harmony with one another. Do not be haughty, but associate with the lowly.(2) Never be wise in your own sight. [17] Repay no one evil for evil, but give thought to do what is honorable in the sight of all. [18] If possible, so far as it depends on you, live peaceably with all. [19] Beloved, never avenge yourselves, but leave it(3) to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” [20] To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” [21] Do not be overcome by evil, but overcome evil with good.
1 Corinthians 13:1-8 & 13
The Way of Love
[1] If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal. [2] And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing. [3] If I give away all I have, and if I deliver up my body to be burned,(1) but have not love, I gain nothing.
[4] Love is patient and kind; love does not envy or boast; it is not arrogant [5] or rude. It does not insist on its own way; it is not irritable or resentful;(2) [6] it does not rejoice at wrongdoing, but rejoices with the truth. [7] Love bears all things, believes all things, hopes all things, endures all things.
[8] Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away.
[13] So now faith, hope, and love abide, these three; but the greatest of these is love.
