[46]While he was still speaking to the people, behold, his mother and his brothers stood outside, asking to speak to him. [48 ] But he replied to the man who told him, “Who is my mother, and who are my brothers?” [49 ] And stretching out his hand toward his disciples, he said, “Here are my mother and my brothers! [50 ] For whoever does the will of my Father in heaven is my brother and sister and mother." (ESV)
Jesus however also looked out for His blood family. One of His final acts as recorded in John 19:26-27 was to look out for His mother even as He was dying on the cross. Yet even in this He did not follow the line of blood vs bond. It was not one of His brothers He assigned to look after His mother, it was His best friend. John loved Jesus and worshiped Him as God! It was this man to which he said, "Behold, your mother!". It was John who then took Mary into his home.
Many Christians refer to their church family and their real family, I refer to my blood (birth) family and my real (church) family. I just don't see that shared ancestors make a family. I'm far concerned with who I will be a million years from now. Those of us who love Jesus share an indestructible bond forged my the blood of Christ. These people are my real family because they are the family I will be with for eternity.
I don't have any blood brothers or sisters yet I consider Jordan a brother who is a friend more than I consider him a friend who is a brother. It may seem to be semantics but it's not. He is my brother not because DNA says so but because the blood of Jesus says so. The same if true with our "friend" Alicia. She is my wife's friend but she is first her sister. When Karina speaks of her she speaks not of a dear friend that would be too low a title. She speaks of her beloved sister. This is our family! These are the ones we love.
It is Alicia who accompanies us on vacation every year. Many people wrongly think she comes with us an a nanny or something. No! She is an auntie who loves her nephew and nieces and who we love dearly. She is a gift from God to our family and as much a sister to Karina as her blood sister is. That is the glorious thing in what God has given us, our family in Him is not in place of but in addition to our blood family. Though in same cases we have chosen to remove certain members of our blood family for various reasons.
As I said earlier, this is no way means we exclude our blood family. I have a sister-in-law that I love dearly and enjoy seeing, I have an aunt and uncle (who also happen to love Jesus) that have been a huge blessing in my life, my wife has a grandfather who I am thankful for beyond words. Larry (Karina's grandfather) is exactly what you might think of when you think of grandpa. He and his wife live on nice seized property with animals for the kids to play with and he takes them on hay rides and shows them the coolest of things. He served his country in Vietnam and was a police officer with the SPD. He is just a cool guy.
My wife's mother and grandmother on the other hand have nothing to do with us and they never will. They are dangerous people, and we will not allow them around our children. They have worked hard to destroy the lives of their children and they would love to do the same to our kids. They are predators who pose physical, mental and spiritual danger to our family. I also have family members we simply do not associate with because. Was it hard to get rid of them? No, because we weren't getting rid of family we were taking out the trash. We still have plenty of family. God has given us a family in Him that is so much deeper than blood could ever run.
Let me be abundantly clear, blood family is great! Ignoring them and just spending time with Christians is a horrible evil and not at all compatible with Scripture. We are called to love and invest in both. I am simply giving God glory for the blessings He has poured on us in Christ, that we may have family that will last for eternity.
