Sin is the blurring of truth which clouds the purity of our consciousness.

Sin is geographical.

Sin is anti-will to God's will; it sets itself to oppose preaching, prayer, and all the institutions of God.

sin is always an offense that touches others, that alters the world and damages it.

Sin is looking for the right thing in the wrong place.
