<Dear Members and Friends:
True forgiveness of a person is important in Christianity. From the prayer Jesus taught his disciples and us, we find:
12 And forgive us our debts, as we forgive our debtors.
13 And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, forever. Amen.
14 For if ye forgive men their trespasses, your heavenly Father will also forgive you:
15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
We also find something about how a person may get tired of forgiving the same person over and over from a question Peter asked Jesus as given below:
21 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?
22 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
