If all people were angelic

(J.R. Miller)

"A new command I give you: Love one another. As I have loved you — so you must love one another." John 13:34

"As I have loved you" means love which is sweet, fragrant, and gentle — to people who are rude and mean-spirited, selfish, and full of faults, with sharp corners and only partially sanctified lives. 

If all people were angelic, and you were too — it would not be hard to love everyone; but as other people are not yet angelic, you will still have need of patience, even if you are angelic yourself, which is quite doubtful.

"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs." 1 Corinthians 13:4-5
