Hearing the malicious rumor, Jesus came face to face with the teachers of the law and publicly tore apart their logic.
Mark 3:23-26 NLT, ‘Jesus called them over and responded with an illustration. “How can Satan cast out Satan?” he asked. “A kingdom divided by civil war will collapse. Similarly, a family splintered by feuding will fall apart. And if Satan is divided and fights against himself, how can he stand? He would never survive.’
This is the report that reached the ears of Jesus’ mother and brothers. In order to avoid discord with the religious community, the family decided to take matters into their own hands and stop this nonsense. Someone in the crowd spotted them and brought it to Jesus’ attention.
Operating in the Word of knowledge, He knew what they were going to say. Operating in the Word of Wisdom, He avoided speaking to them. That’s when Jesus made this profound statement, “Anyone who does God’s will is my brother and sister and mother.”
Allow me to paraphrase. The blood of God’s covenant is thicker than the water of the womb. Jesus avoided His family because they were not united in purpose with Him. He had to unite Himself with others who walked out God’s will in their lives. The relationship with a spiritual mother can be better than one with a biological mother.
That’s what mother means in this verse.
