Good Morning B.. The Bible also tells us to shake the dust from our shoes and walk on.
Matt 10:12 And when ye come into an house, salute it.
13 And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.
14 And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
That being said what kind of relationship do you want with your father?
Do you want the Holidays, Birthday celebrations etc.. or would you prefer the speaking occasionally type? That is one thing you need to decide B..
The 70 x 7 is daily B., and Boy is that a tough one.
Your dad claims to be a Christian and he possibly could be without following the complete teachings of the Bible and God. None are Perfect Save the Lord! Alot of people believe Once saved always saved. So we can't deny he may be saved by the blood of the Lamb. If he is a Christian with Bible Knowledge then he also knows he committed adultery by putting aside your mom and remarrying.
I know a lot of Godly men who have been divorced, some will never remarry. What your dad has done though is repeated over and over again with different women.
It's his choice, his life, as wrong as we feel it is. We can't judge him for his actions. That alone is up to the Father. We may abhor the situations he puts us in. We don't have to roll with it though. There are limits as to what we can tolerate. With Wisdom comes understanding, with understanding, knowledge. We may not always have understanding how a person thinks or all knowledge of their situation, but I think we are Wise enough to know our limits and how to sit them.
Don't put yourself or your children in a place of accepting his behavior but in a place of accepting him as a dad and gr dad only. If that means distance for a while, and sitting up boundaries do it.
Your dad is not a happy person, he won't find happiness through another person. He will have to find the happiness within himself to succeed.
My prayers are with you, love him for who he is not what he has done. Even if it has to be from a distance.
God Bless you and your family
