Isaiah 38:7-8 NIV
[7] “ ‘This is the Lord’s sign to you that the Lord will do what he has promised: [8] I will make the shadow cast by the sun go back the ten steps it has gone down on the stairway of Ahaz.’ ” So the sunlight went back the ten steps it had gone down.//

God has the ability to cause His light to shine where it has previously shined.
