There was an apartment complex that originally had a central heating system. But after an individual heating system for each apartment was installed, the heating bills dramatically dropped. Most people are careful and save what is their own, but they don't save things they share with others. This is because they have selfish-motives and greed. If you have a heart that you want something or you want your family and you to enjoy things more than others, it's difficult to be recognized by God. When you are honest with no selfish-motives, God will repay you with answers and blessing at the right time (Galatians 5:24).
