“For if ye forgive men their trespasses, your heavenly Father will also forgive you.”Matthew 6:14 (KJV)
Forgiveness, reconciliation, and trust are three different things. Confusing them has caused real harm.
Forgiveness is commanded, and it is chiefly about releasing the debt and refusing to carry bitterness. It does not require the other person to have repented, and it does not depend on your feelings settling first.
Reconciliation is a second thing, and it takes two people. Paul writes, as much as lieth in you, live peaceably with all men, which quietly admits it may not always be possible.
Trust is a third thing again, rebuilt over time through changed behaviour. Forgiving someone does not oblige you to return to an unsafe situation, and saying so is not unforgiveness.
A prayer to close
Father, I release this debt to You rather than carrying it. Give me wisdom about what comes next, and keep me from both bitterness and unwise trust. Amen.
