Love the LORD your God with all your heart and with all your soul and with all your strength.
These commandments that I give you today are to be upon your hearts.
Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up.

Matthew  22:37-39

Jesus replied: "Love the Lord your God with all your heart and with all your soul and with all your mind."
This is the first and greatest commandment.
And the second is like it: 'Love your neighbor as yourself.'

John 13:34

"A new command I give you: Love one another. As I have loved you, so you must love one another.

Romans 12:9-21

Love must be sincere. Hate what is evil; cling to what is good.
Be devoted to one another in brotherly love. Honor one another above yourselves.
Never be lacking in zeal, but keep your spiritual fervor, serving the Lord.
Be joyful in hope, patient in affliction, faithful in prayer.
Share with God's people who are in need. Practice hospitality.
Bless those who persecute you; bless and do not curse.
Rejoice with those who rejoice; mourn with those who mourn.
Live in harmony with one another. Do not be proud, but be willing to associate with people of low position. Do not be conceited.
Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everybody.
If it is possible, as far as it depends on you, live at peace with everyone.
Do not take revenge, my friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay," says the Lord.
On the contrary: "If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head."
Do not be overcome by evil, but overcome evil with good.
