There is a poem entitled "Abou Ben Adhem" by James Henry Leigh Hunt we read in high school. It sometimes comes to mind because our teacher required us to memorize it in full:
Abou Ben Adhem (may his tribe increase!)
Awoke one night from a deep dream of peace,
And saw, within the moonlight in his room,
Making it rich, and like a lily in bloom,
An angel writing in a book of gold:—
Exceeding peace had made Ben Adhem bold,
And to the Presence in the room he said
"What writest thou?"—The vision raised its head,
And with a look made of all sweet accord,
Answered "The names of those who love the Lord."
"And is mine one?" said Abou. "Nay, not so,"
Replied the angel. Abou spoke more low,
But cheerly still, and said "I pray thee, then,
Write me as one that loves his fellow men."
The angel wrote, and vanished. The next night
It came again with a great wakening light,
And showed the names whom love of God had blessed,
And lo! Ben Adhem's name led all the rest.
Loving our fellow men is both easy and difficult. People who do us no wrong and who love us are easy to love. But it is difficult to love those who wrong or offend us. if we love this second category of people just the same, I believe we can truly be counted as those who love the Lord.
“If you love those who love you, what credit is that to you? Even sinners love those who love them. And if you do good to those who are good to you, what credit is that to you? Even sinners do that. And if you lend to those from whom you expect repayment, what credit is that to you? Even sinners lend to sinners, expecting to be repaid in full.But love your enemies, do good to them, and lend to them without expecting to get anything back. Then your reward will be great, and you will be children of the Most High, because he is kind to the ungrateful and wicked. Be merciful, just as your Father is merciful." Luke 6:32-36
