In contrast, I think faith is a very logical process. There are elements of giftiness, but in the sense that God often presents Himself before we ask Him to. I have heard of remote villages reporting visitations from God or angels, before missionaries ever arrived.
God's initial contact with humans was one on one.
Faith is a continual building of beliefs, layered with trust. Yes, faith comes by hearing -- it is like putting a layer of roast beef on the sandwich. Then since our trust is built a little by hearing, we put the lettuce on. Then we test whether our faith works, and the layer of cheese is on. Then we read more because the last test worked. It gets thicker and thicker.
My sandwich analogy isn't going to work very long... it will topple over soon. (Time for a faith-switch, faithwich...)
OR, you are given an experience of Gods presence. Either way, you cannot just generate honest faith out of nothing.
A lot of people I know turn to God in a crisis, because they know other people find strength in that. They pray for God to intervene, and He does. It can build from there.
God hears our prayers, and responds. If we don't ask, we have less chance of Him intervening. A prayer can work like an activation... God is always there, but He won't always get involved unless we ask Him to. When we ask, and we see results, our faith is built. When He leads us to information, or we are encouraged by verses, our faith is built up.
Curiosity definitely plays a part. For me, I suddenly realized that I couldn't make sense of the universe unless I applied a creator to the system. Even then it was disturbing, but that's where my search began.
I wanted to find the correct system, so in a sense I wanted to believe in something. I did not automatically believe, but went through a process where I allowed Christianity to make sense for me. Decades later, I am still exploring different concepts and questions. There was a point where I trusted enough of it to head in that direction.
