Salam to all.
Yes, ultimately we need to worship Allah. But there is something else we need to do before that - discover Him.
So, our life’s journey is about that. Some will find reason to believe and others will find reason to disbelieve.
In the end, we will be judged on that.
I have researched over the years and found consistency in the messages of the Books as mentioned in the Quran (that’s a paradox considering Muslims claim the previous Books as being tampered with).
Why this is relevant is because we are learning creatures and the Books taught us incremental knowledge over the course of history.
The Psalms giving us what is Tawheed in Islam (relationship with Allah)
The Torah defining human mechanics
The Gospels introduces forgiveness
The Quran sets the laws for community
Hence the Books are complete with the final messenger and why we should NOT be left behind by adopting any previous Books at the expense of the Final one.
I find this sequential messages sent over thousands of years too incredible to be just coincidental and, for me, is a clear message from a Supreme Being giving us clues, if we want to see it of the truth in the messages sent.
So, it is up to us to find the true message, to discover Allah and to worship him. That is the purpose of life.
Know also that Syaitan (the devil) has made a solemn oath to lead us all astray.... so the path to truth will be turbulent and murky.
All the best.
