Darkness cannot overcome the Light. Darkness in itself is simply the absence of the Light.
Jesus is the Light. Believe in Him and know the truth.
The Light shines in the darkness, and the darkness did not comprehend it.
John 1:5 NASB
Then Jesus again spoke to them, saying, “I am the Light of the world; he who follows Me will not walk in the darkness, but will have the Light of life.” So the Pharisees said to Him, “You are testifying about Yourself; Your testimony is not true.” Jesus answered and said to them, “Even if I testify about Myself, My testimony is true, for I know where I came from and where I am going; but you do not know where I come from or where I am going.
John 8:12-14 NASB
