In science, DNA is the basic code in all living things. The code in our DNA defines our physical characteristics and identifies us based on our lineage. Thinking about our Spiritual life in Christ in terms of DNA (metaphorically) can give us ways of talking about our identity as His people and how that identity in Christ manifests itself as we live out our faith. The identifying marker of the children of God is living in selfless love: “By this everyone will know that you are my disciples, if you love one another” (John 13:35)
