@dga471 has done pretty well in responding to those who often seem to have no wish to understand. I never feel drawn to apologetics to those who perceive no need for God. But St Paul tells me to be prepared to give an account of the hope that is in me, and three people have asked, so I’ll add that to the mix simply for information. But since I was converted at the age of 13, well before reaching Piaget’s formal operations stage, my reasons were not primarily intellectual, so I’m not the best dog for that fight.
My first observation is that any arguments along the lines that scientists cannot consistently be believers is obviated simply by the fact that very many of the best scientists (and philosophers, and statesmen, and technologists etc) have been Christians. And one reason isn’t hard to find - both experience and a body of research show that belief in God is natural to most children unless and until it is educated out of them: the ambiguous power of such education is evident from the fact that we’ve now raised a whole generation of awoke snowflakes because of who runs the educational system. One can, thank God, come to reject indoctrination, but nevertheless it influences demographic belief patterns.
For myself, I was raised in an older, more rationalistic, system, and because of it I almost, but not quite, grew out of my childhood default belief in God, like the rest of my family. I won a place at one of the most academic grammar schools in the country, and got year prizes in a couple of subjects early on. But my main love was zoology - I’d been collecting fossils since I was five and ran experiments in my bedroom - and that’s the subject that later got me into Cambridge with possibly the highest Zoology exam score in the school’s history. I say this not to boast, but to show where my focus lay - and what a prig I was!
So evolution (introduced to me by my agnostic parents) seemed to discount the biblical idea of creation, and my parallel interest in astronomy/astronautics made it seem more likely that a sage like Jesus was a philanthropic extraterrestrial visitor than the Son of God.
But around that time I got to know a bunch of Christians - kids and adults - who were the most interesting and integrated people I’d ever met. I’m still in touch with a few nearly 60 years later, and they’re still role models. They ranged from market gardeners to atmospheric physicists.
Through them, I heard that I was estranged from God because I was a sinner, but that Jesus had died to deal with it. Not a message I liked, either intellectually or as a challenge to my autonomy. But over time I began to long to know God, I eventually (and stupidly without telling anyone at first) “called on the name of Jesus,” and so met him. And here I still am 54 years later, apparently, and have found him faithful through intellectual challenge, failures, illness, bereavement, and the other challenges that life always throws at us. I’ve seen one or two miracles along the way, too, but since I’m assured by commenters here that they don’t happen, there’s no point in talking about that.
From the start I was a minority in my family, and in school. Then I was in a minority at university (though it was impressive that the Cambridge Christian Union alone numbered about 10% of the student population at what was then the best university in the world). I was in a minority at medical school, and was gloomily told that encountering real human suffering would soon sort me out… instead, in something like 1/4 million consultations over my career I saw many patients deal with suffering through faith, and even come to faith through it. And several of my cynical medical school colleagues became Christians (like Jim, who moaned that Christians were always forcing their views down people’s throats, but was converted a couple of years into hospital practice, his Christianity guiding his successful career up to his retirement, since when he’s been in church work).
Along the way I’ve met many people like student Gop Chai, one of the first Christians in Nepal, where there are now anything up to a million Christians despite persecution; Insur, from a Tatarstan atheist family, converted in the Soviet army; a guy whose name I forget converted in prison through reading the page of a Gideon’s Bible he tore out as a cigarette paper, and a bunch of more conventional people who took the intellectual route of examining the historical and other claims of Christianity. A whole library of fascinating individual stories, more often than not in the face of family and peer-group opposition.
But in every case I know, something (grace?) prompted a desire, or a need, to know God, and not the challenge to be persuaded against their will. That’s maybe what that verse in Hebrews means that says “Without faith it is impossible to please him, for whoever would draw near to God must believe that he is and that he rewards those who seek him.” I’m very happy to affirm to those searching that the desire is rewarded, but don’t see much point in arguing the toss with those who want to say it’s irrational. It’s analogous to the way I’m just not interested in being persudaded by those who say that marriage is a bad institution when I, and my family, have been blessed by our marriage for 44 years.
