"But all things become visible when they are exposed by the light, for everything that becomes visible is light. For this reason it says, 'Awake, sleeper, And arise from the dead, And Christ will shine on you.' " - Ephesians 5:13-14 NASB
"For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart." - Hebrews 4:12 ESV
"In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it." - John 1:1-5 ESV
The Greek word there for overcome is katalambano (Strong's G2638) and it speaks of a struggle to possess or best something.
The dark mind can not possess the light. Light must come in and illuminate the darkness. But if light does come in then things get revealed.
"And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil." - John 3:19 ESV
"For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him." - John 3:16-17 ESV
The darkened mind can not come to this conclusion by itself. It must be told. Then when the light truly comes in that mind is illuminated. The light is the light of 'no condemnation'. It isn't just knowledge. It is love and a man who bore our sin for us so we could become the righteousness of God.
Grace coaxes us out of hiding. Grace is the gentle voice that awakens us from sleep by serving us. Rules and regulations just make us want to hide under the covers but grace invites us into the adventure of a new day.
