... a lack of a personal relationship with God
This is
THE reason. In fact every other cause of one "losing their faith" could be summed up as a lack of an
intimate relationship with God. I intentionally did not say a "personal" relationship because having a personal relationship with God (ie what we use to describe our relationship with Him after salvation) and
intimacy with God are two entirely different things.
Think about it. What exactly is faith? Some would quote the verse about "faith is the substance of things not seen, the assurance of things hoped for" but that really is the
end result of faith. It is not how one "has" faith. One gets faith by getting to know the character, nature and behavior of the object of their faith.
For example, if you didnt know me, but i told you i was a financial genius and told you you should invest every cent you can get your hands on a particular investment, how much faith would you have in me? Very little. How much would you risk? Next to nothing because for all you know, i'm a con artist.
If however, we became friends, and you had time to observe that I really did have a good instinct for investments, and though you didnt know me
that long, I had yet to make a bad investment, you would then be more likely to have more faith in me and risk more based on my advice.
But say we got married, and were married for 10 years. You would come to know me intimately. Now you would not only know me in the finance office, you'd know my character and nature as well, and not just how I am in public--you'd know who I
really am. You'd know that I'm honest and ethical and would rather be penniless than make money dishonestly and that I would never suggest to someone they invest in something I wouldnt recommend to my own mother. And you'd also know that in the 10 years we had known each other, you
NEVER knew me to invest in something that I didnt make a huge profit.
How much faith would you have in me then? How much money would you be willing to risk then? Probably everything, right?
Well, it's the same with God. Our faith in him is in
direct porportion to how intimately we know Him. If we dont know Him well, we'll only trust Him with so much.
Those who "lose faith" never really had thier faith based on anything of substance. Their had "faith in faith" not faith in God. Those who truly know God, know that He will NEVER let them down. That faith cannot be lost.

BTW that finance thing was just an illustration. Sorry
