Did God stop the sun, as it says Isaiah 38:8?
Yes, God did cause the sun appear to stop for King Hezekiah, but He also made it run backwards. The indicator of this was the shadow on a sundial. The great debate over this instance focuses on whether the Lord influenced the movement of the sun, the earth, or the shadow itself. Evolutionists like to use this passage to blame the Bible for agreeing with the falsehood that the sun moved across the sky, and the earth remained stationary.
The fact is, the Lord simply said that He would move the sun's shadow. God could have accomplished this task by bending light or tilting the ground on which the sundial rested. I don't see why people think God should have said, "I'll make the earth run backwards for you." The Lord was giving a direct sign that He would give the King 15 more years to live, and it doesn't really matter how He made the shadow reverse itself.
"And this shall be a sign unto thee from the LORD, that the LORD will do this thing that he hath spoken; Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down" (Isa. 38:7-8).
