I was trained/taught in school & college to be an atheist. So is the vast majority of kids in the USA. today.
That brainwashing never goes away but it does make any believe or faith more important.
The stuff they force feed our youth is scary.
I was absolutely flabbergasted when my 15 year old daughter came home from school one day and asked me "Was the bible flood copied from a Babylonian myth? I looked at her with astonishment and asked her where on earth she heard that. I will let you know in a minute.
The following week she asked me "Was the law of Moses copied from the the Hammurabian Code?
I did not have to aske her where she got that from.
This is absolutely astonishing and beyond belief. She was told both the above by her Religious Education teacher.
I couldn't beleive it, I said I can't believe your R/E teacher would say that. I assumed that the teacher would be a Christian just like in my day where that was expected. BUT no her teacher is anti Christian and let's the pupils know it.
Rather fortunately over the last 3 years I have gone down the route of apologetics and I had in my bundles of notes answers to the above questions, along with the the fact that Christmas was not nicked from the festival that celebrated the pagan god Mithra.
My view is that we need to be equipped with what the world is throwing against us and our kids and the vulnerable.
I would also like to add that going down the apologetics route can mess with your head, (as it did with mine for a while) there are some very convincing atheists, Christian haters who can present a very convincing argument, or so they think. Satan will try to use that and render us ineffective, but unless we can defend the faith I would say we are just as ineffective.
So going down such a route we must arm ourselves with what we know to be the truth which is Jesus.
So that we can
1 Peter 3:15-17
But sanctify the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear; having a good conscience, that when they defame you as evildoers, those who revile your good conduct in Christ may be ashamed. For it is better, if it is the will of God, to suffer for doing good than for doing evil.
