How now?

Christianity introduced a merciful, forgiving God who recognised our weakness for sin!

The result: Adopting sin as a way of life with the very small consequence of "saying sorry"

Christians are now lovers of sin as it intrigues them!
I wonder if it Is it possible to find a popular tv show or movie today missing murder, deceit, adultery, fornication, lust, greed, and satanism??

btw Majority of the people acting these things are at church come Sunday!

I've even heard gays and lesbians asking me to cast the first stone if I am without sin!

You have a point @Guru. Just slight addition. Islam is in line with ATR, but bit advanced in the sense that Islam has come to regulate things, which were practiced in the wrong way in ATR.
It regulated it by bringing in limits and responsibility.

Sadly in other ways of life (read religions) like Christianity, it is a license to promiscuity. Because, mostly they go by Western culture or traditions.

Many miss to understand that for Muslims, standards of morality are not set by Western culture or thinking. But it is set by divine revelation.

Also, very importantly
Islam has not come up with anything new.
All the practices in Islam, were noticeable among all ancient communities. Which include African traditions, the Hindu, There was, Babylons, Persian etc

What are these challenges? What is the western brand of thinking/culture and finally what the traditional african 'systems'?

There is something that orginated from their religion.
This is about commemorating the birth of sun god.
I don't mean the "son of God" (inverted comas). This has an interesting origin.

The primitive man in Meditarenian region
..neighbours to the Egyptians.
He could see the sun burning back and forth in the southern hemisphere, receding from them.
And day by day, it started getting colder and colder, 20th of Dec, 21st, 22nd, 23rd, 24th it is getting colder and colder
And on 25th the devil trying to swallow the sun (in the mind of the primitive man).

Actually, these are happening astronomically
..but the primitive man following the sun and could feel the change in temperature and they say now the sins of darkness, the devil has been overcome by the sun.

The sun is reborn
it is born again, the sun coming back on its own on 25th, 26th, 27th etc getting warmer and warmer.

So 25th of Dec was the turn of the tide, in the heaven (i.e. skies).
So the sun is being born, The Sun, not the "son of God".
So this is how the early church adopted an holiday.

This was the pagan holiday
the pagans creates an holiday.
And the Christians saw that these people are acommodative around that day, so they adopted that day.

And they started celebrating Christmas.
