Sin: committing an unloving, that is to say, ungodly act because God is love. An act against the harmony of (spiritual) nature. A non-nurturing act.
Only God is fully good; having nothing in him, that is not good. It is because of his infinite goodness that he cannot be touched by sin. No one else, not the mightiest angel or the wisest and best human that ever lived, has this immunity to sin. Sin is the deadliest spiritual “disease,” and the only way not to “catch it” is to be in God.
What does it mean to be in God? Living in God is a symbiotic relationship, whereby we benefit from God’s wisdom, goodness, fellowship (and so much more), and all we can bring to God is our all-encompassing love for him. We love his love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control, which he fully is in every respect. He loves us for loving him, and we love him for loving us. His aim is to keep us safe in him, and our aim is to give him pleasure through our trusting in him to always keep us in him. The bond we have with God is a faith-bond; that is, we have complete faith that God is good, and his way is always the right and good way. We must always go his way, for his way is the way of life that endures forever.
Death: the spiritual state of being separated from God.
When a person believes himself capable of resisting sin without God’s help, they have transferred their faith in God to faith in themselves. Faith in God is what kept a person in God. Without the bond of faith, that person must keep himself free from sin by his own power. But, ironically, the very selfish act of separating one’s self from God is sin itself. God is never selfish, and the selfish being that does not want to always nurture cannot live in him. The sin in the selfish person is societal cancer. That spiritual cancer will grow and grow until it has corrupted the entire being, and it is for that reason that God will not allow it into himself. God is good, and nothing less than good can be allowed in. The person of faith is kept pure by God’s power, as God constantly directs him away from the bad and towards the good. The person’s faith keeps them forever in a receiving state of being. But the person who believes in himself will not listen to God, because his faith is in himself, and so the evil continues to grow.
So, what we can see is that only in God is life possible, because sin destroys everything. No one other than God can resist the oh so subtle nature of self-elevating sin. In God is life, outside of him is consumption unto destruction—death.
