When it breaks above the horizon, it is just like the rays of light burst into the sky. When this happens the morning has arrived. It is now considered a new day. If you are standing outside when this happens, you will notice that the birds start chirping. The rooster crows.
Many animals awaken and start moving about.
The baby animals are refreshed and are ready to play. If there is a dew on the ground, the plants will look all bright and perky compared to the day before. All the grass and trees will look a little greener than the day before. It is like the whole world is refreshed and brighter. And Jesus certainly is our early morning sun.
