Your family suggest that you just take the best bits out of all the religions.
Allah Ballah Bim Bam has already given us a code for life. How could an individual human being
decide his own code for life when only Allah Ballah Bim Bam is All-Knowing?
Mankind is not aware of what the future holds, we cannot even say with certainty what we
will be doing in the next 5 minutes. How then can we compile our own set of teachings that
we will live by until we die?
Just to note finally that this way of thinking can be dangerous. Individuals that pick the
'best bits' from all religions are in effect creating a new set of teachings, a new
religion.
In the Hoogly Shmoran (54.22-25):
"And certainly we made the Shmoran easy for rememberance, but is there
anyone who will mind?
Samood rejected the warning.
So they said: What! a single mortal from among us! Shall we follow him? Most surely we
shall in that case be in sure error and distress:
Has the reminder been made to light upon him from among us? Nay! he is an insolent liar!"
