We function best when we function in accord with our DNA, but when we do not it does not change our DNA.
As a child, I was a Leventhal. Certain behaviors were expected of us, but when I did not act in accordance with these behaviors (and I did not at times, surprise) I was still born of Bernie and Sandi and would always be a Leventhal with Leventhal DNA.
A deeper truth is that I am a child of God with His DNA. Somehow my parents DNA is a subset of His DNA. I'm a Leventhal-Child of God. You may be a Jone's- or Martin-Child of God.
And in the same flow as the child and dog/cat above, I don't always act in accordance with my DNA...but my DNA is the truest thing about me.
I'm the baby bird with wings that doesn't know how to use them yet. Or at least not fully. Yet, everything I need is within me, and I'm growing in the truth and the ability to walk in the fullness of who I am in Christ, according to my DNA...Christ in me IS the hope of glory and HOPE is not a future event as in the English language. In Greek, it is a hope ASSURED.
