Consider reading the chapter in several translations and choosing a few verses to memorize. I chose:
Luke 6:27-28 NIV
Love your enemies,
Do good to those who hate you,
Bless those who curse you,
Pray for those who mistreat you.
Luke 6:31, 36 NIV
Do to others as you would have them do to you.
Be merciful, just as your Father is merciful.
Luke 6:37-38a NRSV
Do not judge, and you will not be judged;
Do not condemn, and you will not be condemned.
Forgive, and you will be forgiven;
Give, and it will be given to you.
Luke 6:46 NRSV
Why do you call me “Lord, Lord,’ and do not do what I tell you?
