Hi,
If Allah wanted us to be good at worshiping Him---He would have kept us closer to Him.
It's not God's fault it is our fault we don't want to adopt sincere worship. Worship is so many things. One example, refraining from having cliques in society in which one group of best looking people remain to themselves, refraining from that and being inclusive to other Muslims is one act of worship that is more important than Muslims think.
One very large act of obedience to Allah(SWT) is not giving up the truth to advance ones interests or to fit into group of Muslims. We see many people developing worship of their party/government/scholar/sect even it goes against the truth and what God ordained for them.
Another one is not to adopt 'cool' culture. 'Cool' culture is not good and is the way of the Shaytaan. Allah's Prophets rejected 'cool' culture and they were hated by ordinary people. Muslims think it was governments who hated them only, which is not true, even ordinary people hated them and viewed them as losers who are sacrificing personal Dunya for their Lord.
These are just two examples of a list of probably thousands of acts of worship. Muslims ignore 95% of them and thus we have widespread corruption, scholars/imam shaytaans masquerding as men of faith, oppression, clique culture among ordinary people, rudeness, supporting evil, borrowing money and not paying it back, scamming each other, stealing, killing without justification, widespread fornication and lifestyle intended to chase after opposite sex and so on.
For so many people they don't want to sacrifice just chasing opposite sex alone. It is very prevalent nowadays that guys chase after good looking girls for haram reasons and likewise girls try to impress good looking guys and socalize together and do haram acts together. And they recieve praise and cheers from their friends for every 'score'. And then said people will go on Facebook or forums and talk about Muslim Ummah and so on. And I don't mean you, I know you are an elderely sir and respect you.
