Forgiving an unrepentant person does not make us kind it makes us unwise and enablers. To pressure others to forgive those who are not sorry is backwards. The pressure ought to be on the perpetrator to repent and apologize, but we rarely hear that.
It's lazy and easy to "say" we forgive someone, but if it does not lead to reconciliation, then it is not true forgiveness it is smoke and mirrors that lead to arrogance.
God told us to confess when we sin and forgive others when they are sorry. This is for the sake of reconciliation. There can be no reconciliation without sorrow over offenses.
Luke 17:3-4 "…3 Watch yourselves. If your brother sins, rebuke him; and if he repents, forgive him. 4 Even if he sins against you seven times in a day, and seven times returns to say, ‘I repent,’ you must forgive him.”
Why do most people completely ignore the command "if he returns and says 'I repent'"?
To forgive an unrepentant sinner is mean, it does not give the person a chance to be convicted of sin and cleansed from their filthiness. They remain dirty and burdened because no one kept them accountable.
If you care about someone you love, you will warn them, that's the only help that will set them free if they listen and respond according to God's Word.
Ezekiel 3:18-19 "…18 If I say to the wicked man, ‘You will surely die,’ but you do not warn him or speak out to warn him from his wicked way to save his life, that wicked man will die in his iniquity, and I will hold you responsible for his blood. 19But if you warn a wicked man and he does not turn from his wickedness and his wicked way, he will die in his iniquity, but you will have saved yourself. "
Just saying words like "I forgive them" does nothing except build pride in the one who elevates themselves to appear special and good.
Relationships are hard work when done God's way and produce a cleansed life if responded to in humility. The one who sins must humble themselves to be forgiven, and the one keeping their friend accountable must humble themselves in taking a chance on being rejected if the offender refuses to confess their sin.
Psychology based on Darwinism has reversed the order and messed up what truly works. It is not our place to forgive someone who walks in rebellion; it is our place to love them more than we care about rejection.
In our day of apostasy, we will experience lots of rejection for our efforts to help others see what God sees.
By the way, it is lying to say you forgive someone who is not sorry when it does not lead to reconciliation. They are dead words that fall to the ground, meaningless and useless.
Something to ponder and ask God, He was clear about what He said in His word, but most cannot see with Spiritual eyes because their eyes are clouded with worldly psychology.
