"For whoever does the will of my father in heaven is my brother and sister and mother"
Matthew 12:50

I believe that this verse is saying that as you follow God's will you will be able to build a stronger relationship, (like a sibling). I interpret this verse as if everyone who can follow God's will is apart of one large family. When you accept to do what God intends you to do, then you have become apart of this famly. For me this is kinda hard to explain but its like as you follow and grow in God's word, then you can build a better bond as you devote yourself to him.
