TITHES (Have you paid your tithes?)

I was in a youth christian meeting last week saturday and our topic was about TITHES.
Lots of contributions were made by everyone and we read so many bible passages regarding this topic.
It made me realise that I had never paid my tithes ever since I was born, and thats like robbing from God
I'm a catholic and i've never had the importance of this topic stressed before, i'm not trying to raise anything controversial here so plsssssssss don't attack me
We had so many arguments on whether Tithes was meant for only those working or also for students, and we agreed that as a student we receive money from parents or other sources so thats also an earning
We also argued whether the money to get our tithes from included our house rent money or bills, I was like we're not working yet so it doesn't make sense removing from ur rent or bills cos thats the same thing as removing from ur tuition fees & thats insane, God understands all and for now it includes our pocket money, when we start working we can remove from all that
God blesses us abundantly, but I also that those who paid their tithes got theirs in a thousand folds
And I made up my mind that from this onwards I'll always pay my tithes and give atleast 1/10th o f my earnings/pocket money
I can't believe i've been robbing God all this while, God forgive me!
Well our God is ever loving and ever forgiving
I want to ask you this question
Have you paid or do you pay your Tithes?
