The question of identity lead me back to the Bible.
With a quick web search I found:
because those who are led by the Spirit of God are sons of God. For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship. And by him we cry, "Abba, Father."
You are all sons of God through faith in Christ Jesus
Yet to all who received him, to those who believed in his name, he gave the right to become children of God
To revisit the question, "Who am I?" I can truthfully answer that I am a Child of God because I believe it in faith and it is stated in the Word but, what does it mean to be a Child of God? It means we are heirs to his kingdom! Through Jesus's sacrifice we are able to inherit eternity!
16 The Spirit himself testifies with our spirit that we are God’s children. 17 Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
Father God, I can never comprehend the full sacrifice you made through sending your Son to die for me, but I can read your Word and see the message that I am your child through that sacrifice and feel your Spirit well up in me. Thank you for eternity Lord!
