Luke 6:27-35. LOVE YOUR ENEMIES would be one of the high bar that Christ taught to observe. This is agape love, not out of feelings but do the right thing by your neighbour.
Luke 6:27-36
[27]“But I tell you who hear me: love your enemies, do good to those who hate you,
[28]bless those who curse you, and pray for those who ill-treat you.
[29]If anyone hits you on one cheek, let him hit the other one too; if someone takes your coat, let him have your shirt as well.
[30]Give to everyone who asks you for something, and when someone takes what is yours, do not ask for it back.
[31]Do for others just what you want them to do for you.
[32]“If you love only the people who love you, why should you receive a blessing? Even sinners love those who love them!
[33]And if you do good only to those who do good to you, why should you receive a blessing? Even sinners do that!
[34]And if you lend only to those from whom you hope to get it back, why should you receive a blessing? Even sinners lend to sinners, to get back the same amount!
[35]No! Love your enemies and do good to them; lend and expect nothing back. You will then have a great reward, and you will be children of the Most High God. For he is good to the ungrateful and the wicked.
[36]Be merciful just as your Father is merciful.
