'That's' in the Bible

Therefore I tell you, her many sins have been forgiven; that’s why she loved much. But the one who is forgiven little, loves little.”

“That’s how it is with the one who stores up treasure for himself and is not rich toward God.”

If that’s how God clothes the grass, which is in the field today and is thrown into the furnace tomorrow, how much more will He do for you—you of little faith?
