i can't speak for pianowelsh, but for myself, it can be with sensing the 'circle of life.' you are born, you grow and mature, you start noticing things that are 'constant' vs things that are 'inconsistent.' whether it is things that affected you positively or negatively that you have had time to think about- or sudden crisis that make you question things all in one day.
all of us have probably had difficult childhoods in one instance or another. for me, i lost my father at 2 years of age. this forced me to look elsewhere for a father - and my heavenly Father is probably closer now to me because i often prayed even when i disbelieved. i never felt unheard, just misunderstood at first. then, i realized 'we come to God, respectfully and not demandingly.' as humans, this is hard. we want God to come to us. it is almost unheard of in this society to have the respect that God requires. we are told that we are all equal. well, we're really never going to be equal to God - but if we are humble 'he will lift us up.'
this is a very hard idea - and why christianity is often thought to deny us our freedom. actually, with discipline is more freedom. just like when you take lessons. you usually do what your teacher suggests - out of respect = and then you see you have more freedom later as they let go of you more and more. God speaks of rewards. the rewards don't have naything to do with our deserving them - but have a lot to do with our listening and respecting abilities. if we are 'soldiers' for Christ, it means that we follow without disbelief and questioning. that's also a hard idea - and better able to be done when we trust God. coming to trust God is when we see that even the animals are cared for, and he cares enough to tell us what he has in store for us (the kingdom of God) that 'eye has not seen, nor ear heard.' just as orgasms seem the limit to pleasure now - he says we will have pleasure forever more. maybe we'll hear good music, who knows. but, we know that if he can make sex, he can make something even better.
i ramble too much at night.
