God was creating more time for King Hezekiah. God gives us our time and knows exactly how much he gives us. The same can be said of nations. Once there was an important battle involving the Israelite army God wanted them to win, and, to allow them to win he made the day oftbe battle longer so the enemy couldn't escape in the darkness. There are many stories and passages in the Bible that assure us that God is the source and creator of time.
Scripture teaches that time wfll run out for the whole world and everyone living.
The last book of the Bible tells us how time will end for this world and how God will create a new and wonderful world where time will never run out. The first book of the Bible teaches important things about God's creation of time. We are told how God created the whole universe including the days and nights through which the universe exists and moves. God created days and nights. Once a moment of time has flowed by us into the past, there is nothing we can do to change it, so God wants us to treat each moment wisely and faithfully.
