“Who is my mother and who are my brothers? [Pointing to his disciples] Here are my mother and my brothers. For whoever does the will of my Father in heaven is my brother and sister and mother.” (Matt. 12:48-50)

Jesus is teaching two key understandings regarding spiritual life here.

The first is that we are not these physical bodies:

We are each spiritual beings, wearing temporary physical bodies. Therefore, while we might love and respect the mother of this body, that body that gave birth to our body is being driven by a spirit-person who is also not their physical body.

Similarly, our brothers and sisters of this body are also spiritual beings temporarily residing in their physical bodies, which happen to have been born from the same physical body ours was born from.

So who are we, the spirit-persons, related to? Who is our real mother, father, brothers and sisters?

The Supreme Being is our real Father. He is also our Best Friend and our constant Companion.

Jesus confirms this as he explains that his true mothers and brothers are those who are executing their original position as loving servants of the Supreme Being - as he pointed to his disciples, saying:
"Here are my mother and my brothers. For whoever does the will of my Father in heaven is my brother and sister and mother.”
Those of us who rebel against their innate relationship with the Supreme Being - as most on this planet have done - have disinherited ourselves from this loving family that Jesus is speaking of.

We are each constantly wanting to be part of a family. When we are young we cling to our family, and when we get older we want to have our own family. This desire for family is innate within us because we have a permanent family that we have disconnected with.

This is our spiritual family - headed up by the Supreme Being.

Jesus' statement, "whoever does the will of my Father" also means that each of us can become reunited with our real family at any time. At any time we can choose to resume our loving service relationship with the Supreme Being, and join our real family members in loving and serving the Supreme Being.

And what is the "will of my Father"? Jesus clearly teaches what will please the Supreme Being. The Supreme Being wants us to come back to Him. He wants us to return to His loving arms. What else would we expect from a loving Father?
" 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment." (Matt. 22:37-38)
