Jesus Culture is the true Counter-culture

"Brother" in biblical context is used many times as a description of our kinship among believers. This is where we get the phrase "my brother in Christ..."

In Mark 3 where Jesus heals the sabbath we read this:

31Then Jesus’ mother and brothers arrived. Standing outside, they sent someone in to call him.
32 A crowd was sitting around him, and they told him, “Your mother and brothers are outside looking for you.”
33 “Who are my mother and my brothers?” he asked.
34 Then he looked at those seated in a circle around him and said, “Here are my mother and my brothers!
35 Whoever does God’s will is my brother and sister and mother.”

God's use for our love supercedes the aspects of genetics, which includes the appearance it gives us in flesh, which will be altered, damaged, stained, removed, repaired. It does no use to fixate on our flesh's appearance as an identifier of our spirit, because our bodies will be left behind when the spirit passes on.
