We stumble through life because we walk in darkness. We walk without the light.

Be determined to walk in the light, for God is the light.

John 11:10 (KJV) – but if a man walk in the night, he stumbleth, because there is no light in him.

I John 1:5 (KJV) – this then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
