Sin

At its most fundamental level – sin is death. For the wages of sin is death (Romans 6:23). The fact that we die is not a punishment sent to us from God but the result of our having broken fellowship (communion) with God. God is Life and the only source of life. Created things (humanity included) do not have life in themselves, it is not something we have as our possession and power. Rather, life is the gift of God. It is not just our life that is the gift of God – but our very existence and the existence of all that is. God is our Creator. The Scriptures say, “In Him we live and move and have our being” (Acts 17:28).
Genesis offers us the story of Adam and Eve in which we hear described their disobedience from God. He had warned them: “Do not eat of the fruit of the tree of the knowledge of good and evil, for in the day that you eat of it you shall surely die.”
Many early commentators on Scripture were careful to note that God did not say, “In the day you eat of it I will kill you,” but “in the day you eat of it you shall die.” Rather we are told: “God did not create death, nor does he delight in the death of the living” (Wisdom 1:13).
St. Athanasius explains that when humanity chose to break its relationship with God (through disobedience) we cut ourselves off from the source of life. However God did not take life from us (He does not take back the gifts He gives) but we removed ourselves from it. And so we die. We not only die physically, but we have a process of death at work in us. St. Paul speaks of this process as “corruption.” This movement away from and towards death and destruction reveals itself in the many broken things in our lives. We hurt and kill each other. We hurt and destroy creation. We are weak and easily enslaved to powerful things such as drugs and alcohol. We are dominated by greed, envy, lust, anger, etc. We cannot help ourselves in this matter because we do not have life within ourselves. Only God can give us the true life that alone can make us well.
