You say that an apology is not necessary for someone to forgive. Yet, isn’t an apology a good thing?
Yes, an apology from the one who offended can go a long way in helping a person to forgive and in repairing a damaged relationship. Yet, I say it is not necessary because forgiving is an unconditional response by the one offended. Offended people should be able to forgive whenever they are ready and have chosen to forgive. This is a freedom that belongs to those who are offended.
