The reason why some people become great lieyers, is because of their empty promises. Our politicians to rank first. When it is a campaign time, they will come with a tall list of projects. Fixing the road, construction of community KVIP, and many more. The fact is that after election will not see them again.
For a whole 4 years in office, only streets light that he was able to fix. Empty promises. When he is passing by during the election season, the glass are down but after winning the election, the glass is up. It not their fault, it ours.
You know that you do not love that girl but just want to go into bed with her. Making all the empty promises. I will do everything for you, I will love you ti I die, I will die for you and all the sweet words that you could use empty promises.
The Bible says, sorry for he that made promises and does not redeem, it's better you don't made them.
Conclusion
Be mindful of making your promise, it's better your don't.
As for politicians, they ought to be legally responsible for what they promise before an election. Politics has become a freezone, where fraud and deception are allowed without anyone being responsible for it.
