Obedience is thicker than blood.
While Jesus was still talking to the crowd, his mother and brothers stood outside, wanting to speak to him. Someone told him, “Your mother and brothers are standing outside, wanting to speak to you.”
He replied to him, “Who is my mother, and who are my brothers?” Pointing to his disciples, he said, “Here are my mother and my brothers. For whoever does the will of my Father in heaven is my brother and sister and mother.” Matthew 12:46-50 NIV. See also Mark 3:31-35 and Luke 8:19-21
Jesus responds to question concerning his mother and brothers in three of the four gospels. At the time he shares this wisdom with his followers, He is in the midst of explaining the Kingdom of God using parables. In the Gospel of Matthew, He has just warned people about evil spirits and protecting themselves by keeping their eyes on God continually to prevent re-infestation of evil. In Mark, He has just warned people about blaspheming the Holy Spirit. In Luke, He has just warned people to spread God’s wisdom and light and not to keep it hidden.
Jesus is calling us into a “one-on-one” relationship with God. It does not mean we do not care for or receive care from our “earthly” family, but it does mean that we need to seek God first and listen to Him independently of others. And remember, once we “hear” we need to be obedient to what we have heard from God.
He replied, “My mother and brothers are the ones who hear and do God’s Word. Obedience is thicker than blood.” Luke 8:21 The Message
