It is often in our darkest hours that we turn to the Lord, only then realizing that He was there, waiting for us, all along. Darkness is no obstacle for God. In the first day of creation, He created light and divided the day between darkness and light. While God's light is eternal and can reach anywhere, darkness also belongs to Him. Darkness hides nothing from Him. He can use darkness as well as light to bring about His works.
We are often afraid of the dark, of the uncertainty that it presents to us, of the confusion that it brings to us. So too do we stumble through the uncertainty of our future and the confusion of the times we live in. To us, the future is in darkness--which can be frightening, even terrifying. However, God speaks to us through that darkness, guaranteeing a wondrous future beyond our wildest imaginations.
Do not be afraid.
