You want to know why kids today don't believe in religion as much as their parents?
The Internet. Why? Because kids are naturally curious.
"Why is the sky blue?" "Where do clouds come from?" "How does the sun know when to get up?"
These are all questions that every parent gets, and many cannot answer in a manner that the children find acceptable. So what do they do? They talk to their friends, sign onto the internet and start looking for answers.
The problem isn't in the seeking of knowledge and truth, the problem comes in when the parents cannot answer the questions that the child asks about faith. When they are told "thats' just the way it is", they tend to look around to see if there is something else that the parents missed.
When the child finds out that its based on a non logical story, they then think it doesn't work and go on to find something else that will give their lives meaning.
I had the same crisis of faith myself, because growing up in foster care, each family I was placed with told me that the people I'd just left were heathens, and if I wanted to be saved and considered good, I had to believe as they did.
After about 5 or 6 of those, I kinda thought Christianity was a crock, which is why I became a Taoist.
However.........Tao is a philosophy rather than a religion and teaches you to examine everything. I applied it to Christianity and found out something interesting.
For a religion that is supposed to unite all mankind, people of various denominations are so busy showing that their way is the "right" way, to the exclusion of all others (watch Northern and Southern Baptists go at it sometime), because they want to be "first" in Heaven.
Interestingly enough, everyone gets in. See the Lost Gospel of Thomas that was recently discovered and verified as authentic.
Like I said, for a religion that is supposed to unite all mankind, it does a really good job of dividing them.
