'Resentment' in the Bible

‘And forgive us our debts, as we have forgiven our debtors [letting go of both the wrong and the resentment].

For if you forgive others their trespasses [their reckless and willful sins], your heavenly Father will also forgive you.

But if you do not forgive others [nurturing your hurt and anger with the result that it interferes with your relationship with God], then your Father will not forgive your trespasses.
