“Let no man pull you so low as to hate him.”

The Martin Luther King, Jr. Memorial, a 30-foot statue on the National Mall, was erected in 2011.

Celebrate Martin Luther King Jr. Day this Monday with fifteen of his most poignant quotes—some you may have heard already and some you probably haven’t—but all of them worth repeating and contemplating on this holiday of remembrance, service, and equality.

 1. “We must accept finite disappointment, but never lose infinite hope.” 

 2. “Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.”

 3. “Forgiveness is not an occasional act. It is a permanent attitude.” 

 4. “I have decided to stick with love. Hate is too great a burden to bear.”

 5. “Faith is taking the first step even when you don’t see the whole staircase.” 

 6. “Life’s most persistent and urgent question is, ‘What are you doing for others?’”

 7. “Never succumb to the temptation of bitterness.”

 8. “Our lives begin to end the day we become silent about things that matter.”

 9. “We may have all come on different ships, but we’re in the same boat now.” 

 10. “The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.”

 11. “Change does not roll in on the wheels of inevitability, but comes through continuous struggle.”

 12. “Love is the only force capable of transforming an enemy into friend.” 

 13. “There comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because conscience tells him it is right.” 

 14. “Let no man pull you so low as to hate him.”

 15. “If you can’t fly then run, if you can’t run then walk, if you can’t walk then crawl, but whatever you do you have to keep moving forward.”
