John:12:35-36
akjv@John:12:35 @ Then Jesus said to them, Yet a little while is the light with you. Walk while you have the light, lest darkness come on you: for he that walks in darkness knows not where he goes.
akjv@John:12:36 @ While you have light, believe in the light, that you may be the children of light. These things spoke Jesus, and departed, and did hide himself from them.
