“My son, do not make light of the Lord’s discipline,
and do not lose heart when he rebukes you,
because the Lord disciplines the one he loves,
and he chastens everyone he accepts as his son.”
There is the question posed by teachers how one could be forgiven again when they’re already forgiven. There is more than one example of the former from Jesus, but here is the one from the Lord’s/Our Father Prayer with some words that follow. Followed by a passage in the letter to the Ephesians that makes the latter point.
And forgive us our debts,
as we also have forgiven our debtors…
For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins.
Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.
It’s not like we haven’t been forgiven through Christ’s death on the cross, because we most certainly have (Hebrews 10). It’s the reality that we live in relationships which need ongoing attention and repair at times. And it’s not like the relationship is at all in danger of being lost. A wayward child forever remains the child of his parent. But the relationship for all practical purposes might be completely lost if parent and child separates and communion is lost. A good parent’s heart is grieved; for that matter, it can be the other way around, the heart of a child broken over a difficult parent.
We in and through Jesus are forgiven already, so that we shouldn’t be in fear of condemnation or eternal punishment. But in the immediate life in which we now live, when all is not entirely healed and we still can and do sin, ongoing forgiveness in a kind of family setting is not only desirable, but even necessary. We might simply forgive apart from confession, though for the good of the other, confession might be helpful and formative for them.
We are forgiven in Jesus, and through that forgiveness we can forgive others. And know the ongoing family love of God in both giving and receiving ongoing forgiveness as needed day to day in and through Jesus.
