Conclusion: So Who Are You Really?

The above essays illustrate the science behind our real composition: As spirit not the physical body.

The question remains then, who are we really? Yes, our composition is spirit not matter. But our actual identity isn't just our composition: It also refers to our real nature and position - what is our role, why we exist and what makes us happy.

As the scriptures, Jesus and all the prophets explain, our identity relates to our position with respect to the Supreme Being. Namely, we are each children of the Supreme Spirit.

And our identity is part of this relationship. But our relationship with God runs deeper than simply being one of His children. We are also the Supreme Being's loving servants. Jesus explains this relationship clearly:
"For whoever does the will of my Father in heaven is my brother and sister and mother.” (Matt. 12:50)
Jesus also explains that returning to the spiritual realm relates specifically to whether we want to assume our natural role as God's loving servant:
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven." (Matt. 7:21)
Even understanding Jesus and his teachings depends upon whether we are interested in serving God:
"Anyone who chooses to do the will of God will find out whether my teaching comes from God or whether I speak on my own." (John 7:17)
Thus we find our true identity - our role and relationship with the Supreme Spirit: We are each one of God's loving servants. While our constitution might be spirit, not matter - our identity is loving servant to the Supreme Spirit. This is why each of us yearns to love someone - and serve and please the one we love. This is why each of us searches for our soul mate in life - that perfect person for me: Each of us is seeking to reclaim our lost loving service relationship with the Supreme Being.

Jesus admitted his own position as God's loving servant:
"By myself I can do nothing; I judge only as I hear, and my judgment is just, for I seek not to please myself but Him who sent me." (John 5:30)
Wanting to please God is based upon love: Wanting to please the one we love. And such a relationship of loving service is not the same as slavery. The very fact that we have the freedom to decide whether we want to serve God or serve ourselves specifically illustrates that God gave us the freedom to love Him or not: He could certainly force us to serve Him. But He doesn't. This is because love requires freedom.

And it is this loving relationship - with the Supreme Being - that fulfills and completes our identity. This is why Jesus' most important instruction was:
"'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)
