And what about those who have not repented. Or have not reached out to you for forgiveness.
Are we supposed to forgive them?
The Bible has so many examples and instructions concerning forgiveness, the matter is of Christian
commandment status. Failing to forgive risks not being forgiven by God of one's own sins. An unbeliever is not expected nor required by scripture to return forgiveness nor stop offending, but must be allowed ongoing forgiveness from Christians offended. There are exceptions for a spouse concerning adultery in Mt 19:9, and abandonment in 1 Cor 7:12-15. Even with those it is terribly unhealthy for the offended to not forgive when moving on towards change and healing, else healing is delayed, and egregious sorrows taken in to a new relationship.
Matthew 18 covers issues between Christian brethren especially those of the same congregation. As mentioned already above, the act of one-way forgiveness keeps the forgiver freed from sorrows if we let that work in us. That also makes possible freedom of added sorrow of the offender.
Working with Teen Challenge men I learned the power of this when moving a man to forgive a father, mother, others that abused or neglected them. Forgiving without condition easily gives an abuser release, rest, healing since they likely are inwardly troubled over their own behavior. A father might not want to forgive a wayward son who hugs him forgiving, whether dad remains convinced he handled his son properly, but when forgiven the dads/mothers/siblings, other people involved often change to the better towards son or daughter, maybe very slowly, but with cautious improvement, healing. The ones offended should be the first to forgive so as to move on past it, shedding such burdens.
Do a Bible search for "forgive" to nail this down. There are many free online Bible apps with lots of tools for research.
