In the name of Allah the most Gracious the most Merciful,
I will first present a story to you,
I am a manager in a factory and have applied certain rules and obligations towards it, such rules are applied to whoever is working in the factory. I am in need of a single labour/worker for checking the semi-finished product. I appoint you for such wage and for a certain time period.
Now what you do is instead of deficating yourself to work, you are going around and doing as you please or taking the waste, dublicate and extra material without permission, drinking while workig etc. but mostly you are doing is not interacting with your co workers about work concerns and going against the rules i have applied to all.
The rules in the factory telates to the legal and illegal things Allah has obligated on man kind, the work is worshipping him only in obedience and faith, so this should explain to you that he is the owner of your soul and he can take it away. You have come to this world for a certain objective and that is to collect good deeds and worship Allah only for Akhirah.
And in hope that you will in shaa Allah leave all the bad you do or sin, Allah do not like he transgressors but loves to forgive who ask for forgiveness. :)
