Hi Evan Williams,
I suppose a good example that illustrates an answer to your question is straight from the Bible (see Acts 10:1-48). There was a man named Cornelius - a religious man who constantly prayed to God - and asked the Lord to reveal Himself to him. Cornelius may have known or heard of Jesus, but evidently not His plan of salvation. God heard and answered his prayer by sending St. Peter to preach the Gospel to him. It may not be as spectacular as that for many, but sometimes God can just use a constant friend or a complete stranger just "coincidentally" being at the right place at the right time. I believe that Billy Graham heard the Gospel message one night because a Christian gave up his seat in the church for him. Coincidence? I don't think so. We know that God is unchanging (James 1:17) and so if He heard Cornelius' prayer, He will also hear the prayers of those who do not know Him but desire to.
I believe that if someone really wants to know God that He
will make Himself known to them in some fashion or another. Why? Because He promises that if someone keeps seeking Him they'll find Him and more than that, it's exactly what He wants!
I don't think so much that the issue is that people are born in a different culture and being brought up with different beliefs because there are millions of Christians all over the world who came from just that kind of background! Some were Muslims brought up in a strict Islamic family, others in an atheistic, Buddhist, and Hindu families. Many of those Christians all over the world face persecution just for making a stand for Christ. The real issue is whether they want to lay down their pride, step through their fears, and take up their cross and follow Jesus upon hearing the Gospel message.
For those who have never heard of the Gospel message we just have to believe that God is sovereign and righteous judge such that He will do what is right. I mean, this is the same God who - for the sake of ten righteous people - wouldn't destroy a city of thousands of very evil sinners (Genesis 18:32). We see time and time again - both in the Old Testament and through the life of Jesus - who God is and how He operates and that gives us hope that He will do what is right. When everyone wanted to stone the woman caught in adultery, Jesus forgave. That's just who God is. God is just and will always act in line with that. Our sense of justice pales in comparison to Him who
is justice. It's interesting, whenever the Bible talks about the Judgment not once, not once, does it ever mention people saying that "It's not fair."
Furthermore, St. Paul tells us that God has revealed Himself to everyone through what He has created in nature (Romans 1:20). For example, just looking at the beauty and complexity of nature we can see that God is all-powerful, a God of order, and is personal (given the attention to detail and complexity in the creation). The fact that the Earth is perfectly created to support life on Earth (i.e. the anthropic principle) indicates that God (or the creator) is good and faithful. This is just a basic illustration of what people can and should deduce from looking at nature. Even the bloodshed in the world should give people a sense of
there's something not right with the world and that would be caused by sin. I'll just be sitting there watching the news, seeing the death and suffering and I just know that this isn't how it is supposed to be. People's conscience and that yearning for eternity are other examples of things that God has put in place to reveal Himself to humanity.
So... this leads me to the following question. Isn't it a little unfair assuming that the Christian God is real that some of us are born into a Christian lifestyle and will easily be persuaded to believe in Yahweh and Jesus whereas others are put through an incorrect indoctrination and must fight the incredibly unlikely odds of converting?
Ironically enough, I think that Christians who were unbelievers first perhaps have an advantage in that they know how empty that life is and can see His provision in their salvation. In some areas of the world where their family would attempt to kill them for conversion to Christ they experience God to a greater degree because as St. Paul notes that suffering accelerates spiritual growth and reliance on God. Christians who were raised in a Christian environment and family don't really have the contrast that Christians who were born into an unbelieving family have. As an aside, if you can be "persuaded to believe" you can be persuaded out of belief. As I mention later I think that most Christians have faith that has stood the test of fire.
I mean... let's say you are born into a radical Muslim family. Chances are you will be raised to despise Christianity
Perhaps, but don't you think that God is bigger than all of that? Some of the most extremist people have come to faith in Christ. A good example of how God can reach people regardless of their upbringing is Mosab Yousef - the youngest son of one of Hamas' founders - came to know Christ. His book
Son of Hamas outlines his journey. That's testimony to the power of the Gospel's transforming message. I've never been in that situation so I can't speak with any authority on it, but I think that the sort of unconditional love and grace that Jesus has shown and gives is strong enough to break through any hatred and pride.
It just seems like the vast majority of us believe whatever we happen to be told first as children and then stick with that idea for the rest of our lives (with a few exceptions). Technically, we are all born atheists.
Correction: we are born sinners with a natural bent away from God - it is our nature. When we are born we do not have any cognitive abilities and so one cannot be an atheist or anything else, for such a belief requires, by definition, an intellectual conviction. However, the Bible tells us that God has placed eternity in the hearts of mankind and I believe that deep down people know instinctively that there's something more to life than what we see.
As an aside, you can't talk about "indoctrination" solely for God believing families. Do not atheistic families also - by their very actions, attitudes, and faith (or lack thereof) - foster the same ideals in their children? You can't have it both ways.

I don't think that the whole indoctrination argument holds any water regardless, as indoctrination - contrasted with education - involves processes and strategies and the expectation that the indoctrinated person will not question or critically examine the doctrine that they have learned. I know of
no Christian family or Christian who is like this. Do you? Many
cults are guilty of using indoctrination methods, but I know of no Christian church that does. Contrary to what the atheistic straw-man argument says, the Bible challenges man's thinking - for example, see God's challenges to Job and His challenge to "taste and see that the Lord is God," the logical arguments that St. Paul uses, and Peter's exhortation to always "be ready to give an answer" to anyone who asks re the hope that we have.
It isn't indoctrination to tell your children what sin is and that Jesus is the answer to sin. Even as a child I realised by myself that I was a sinner (e.g. I had lied) and that I needed God to forgive me. Maybe I didn't understand it on the level that I do now, but I still knew and that is the strength of the Gospel message: It's so simple that it is applicable to everyone from children through to people at the end of their lives.
To me at least, it seems that the only reason you've probably ever believed in that God is because you were born in a Christian setting.
That would fly in the face of the millions of Christian converts world-wide..
For me personally I was born into a Christian family. But I went my own way during my late-teen and early-twenties years doing all the stuff the world says should make me happy, and my conclusion is much the same as King Solomon's in Ecclesiastes: It's all pointless. I now know, after living in a life of sin, that God's way is the best way. I regret the life that I lived and if I could go back and have the option to redo it I'd definitely follow God's way. It's just one of those things that you have to experience for yourself. You know, it doesn't matter how many times it is written in the Bible it doesn't "seem real" until you do it and then see the reasons for the command against it. God's unconditional acceptance and grace is also something that draws me to Him ... it's something that I've never really had. That the God of the universe could care about me, let alone die for me?
In addition to that emptiness that I just couldn't fill, I had doubts regarding God, His faithfulness and sovereignty, the Bible, and everything else. I've done a lot of research and listened to that many messages that I know now that my faith has a very reasonable foundation. I don't believe because it is the religion that I was brought up in and if that is the sole reason for one's belief the question has to be asked whether it is even genuine or sincere? Faith in Christ is a commitment made from our heart and mind. The Christian life - as I'm learning - is much more than mere academic knowledge. It's about an active fellowship with God. I see that Christianity is genuine and reasonable - both experiential and academically.
