Abiding in the Lord is what keeps us on the right path and in His light. Otherwise there is only darkness.
Be a witness for Christ. Allow the Lord to use you for His kingdom. Follow His counsel and be led in His light.
John 8:12 (KJV)
12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
