Passage
So also shall my heavenly Father do to you, if you forgive not every one his brother from your hearts.
So also shall my heavenly Father do to you, if you forgive not every one his brother from your hearts.
Matthew 18:33 Shouldst not thou then have had compassion also on thy fellow servant, even as I had compassion on thee?
Matthew 18:34 And his lord being angry, delivered him to the torturers until he paid all the debt.
Matthew 18:35 So also shall my heavenly Father do to you, if you forgive not every one his brother from your hearts.
The verse centers on "shall", "heavenly", "father", "forgive", "brother", and "hearts". It is saying that the verse draws attention to "shall" and "heavenly", so its meaning should be read from those terms before moving to application.
The prior verse says "And his lord being angry delivered him...", giving immediate footing for "shall" and "heavenly". In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "shall" and "heavenly" with trust shaped by these words, not by a vague optimism outside the passage.
