Why do you do good?

Something that my mum said angered me greatly and got me thinking about a few things.
For context, I did something which she perceived to be wrong.
She then said to me 'If you keep being like that, you will lose your blessings (from God)'

Ok, join me in a collective 'wtf' together. 1... 2.. 3. No? You don't see why it's ridiculous? Let me elaborate.
