Matthew and Luke report different discourses following our Lord’s instructions on prayer. Matthew tells us about consequential or “on demand” forgiveness. Luke connects a parable about the necessary movements of friendship.
Our Lord addresses how we pile the need of one friend onto another friend. It is a kind of impertinence. My friend’s friends are not necessarily my friends, but a need is a need.
For if all of you forgive men their trespasses, your heavenly Father will also forgive you: But if all of you forgive not men their trespasses, neither will your Father forgive your trespasses.Matthew 6:14-15
The parable reported by Luke sets up a landmark of generosity.
And he said unto them, Which of you shall have a friend, and shall go unto him at midnight, and say unto him, Friend, lend me three loaves;Luke 11:5
