The Bible says to honor your father and mother. It doesn't stipulate if they are bad or good. My mother gave me up when I was a little baby, but I still love her because I have no idea what her life was like at the time. My Dad died very young by his own doing. It doesn't matter....both of them gave me life, and I thank and love them for that. I had a step mother for 7 years of my young life that was a troubled soul, who took it out on the weak. How miserable she must have viewed her existence. I pity her today because she was a lost soul. How poor and wretched people like this become, and their days are full of sorrow. They are to be pitied and forgiven, as the hell they live in is perpetuated by themselves. The person that said their mother acts like she doesn't remember how she was to her children, is misinformed. Her/his mother does remember, but wants to forget. You can help her do that. She probably is so ashamed of the past, that she wants to forget it and try and do better. Give her that chance.
I have wonderful mothers, fathers, sisters, brothers, etc., in my spiritual family, and believe me when I say that I couldn't love them any more than if they were my own blood. You can find spiritual friends and family that are more dear to you than any family member. There is a lady right here on this forum that has become like a sister to me and we have never met yet......someday we will.
Being a single parent myself in the past and raising a child was not easy. Did I do everything correct? No. Times were hard, money was scarce, I did my best. Last night as I was talking to my son late into the night, laughing, crying, praying together, it seemed that whatever I lacked in raising him, God did the rest. He has turned out to be a fine man, father, husband, and provider for his family. Respected by everyone.
Forgiveness of strangers is pretty easy, but when it comes to those we love and look to for trust and acceptance.....that's difficult when they fail us. Especially family members. What we need to realize is that we are no picnic either with all of our shortcomings. Forgiveness actually heals yourself, not the other person. It releases your spirit and gives you peace and the victory in the situation. If you find yourself always remembering negative past situations to repeat it over and over again.....you have not forgiven. No, we can not forget, but we can learn to not let those thoughts "dwell" in our mind. I remember a saying: "You can't help the birds flying over your head, but you can keep them from building a nest in your hair". Get a list of wonderful times that you have experienced in your life, and then when the negative thoughts come, take out that list and read it over and over.
There are times when forgiveness is especially difficult for people. Victims of abuse come to mind. Asking God to help you forgive, can release you from that bitter bondage of memory. There is such a blessing in forgiveness that is healing to the soul. Easy? No. Necessary? Absolutely.
