Truly He taught us to love one another. His law is love and His Gospel is Peace.
For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.” - Galatians 5:14
"And this is love: that we walk in obedience to his commands." - 2 John 1:6
‘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.' - Matthew 22:37-39
