Even time had to slow down.

When God answers our prayers, nothing is impossible.

Mountains can be moved, evil things can turn to blessings.

Even time has to obey, when God commands it to stop.

One of the greatest enemies of prayer is distraction.

King Hezekiah had a good solution for it in Isaiah 38:2

He turned his face toward a wall and prayed to the Lord.

God heard his prayer and gave him fifteen more years to live.

I'm sure, after that, 

 the king was always eager to go back to the wall

and pray again.
