Spirits, Truth, and Senses

Just some ideas that have been wandering around in my head; thought I'd take a moment to get them out before they slip away.

Spirits.
How do we inherit some things that are just inherited talents, traits, and things that don't make sense to inherit from our genes?  Do we inherit spirits from our past and carry them forward?  Is this why it's so important to stay in touch, learn, and understand our roots, our past, our history?
I have been undecided on whether or not I feel spirits are "recycled" but I think there could be some truth to our ancestors' spirits propelling us forward.  Not that we re-use them, but they combine and move forward with us.

Knowing & Speaking Wisdom from our God.
Many times throughout the past people have claimed to have spoken with the voice of God.  Do I believe it's possible?  Well sure.  Why?  If God lives through everything else that lives, then naturally those with voices will speak the truth of God's words from time to time. 
Sometimes I think or feel something to be true with such certainty, without not necessarly always knowing why.  We call it instinct.  But, what gives us instinct?  ... there ya go.

Senses.
Sensing things is not some mysterious unnatural thing.  People sense things all the time that are out of the ordinary, yes, but they are totally natural.  Humans fantasize a lot of fantastical things with our imaginations, particularly when it's something we don't understand clearly.  But that which is here upon this earth is very natural, and very understandable, if not by everyone all the time.
How do you think those amazing cancer sensing dogs "sense" the cancer in people?  With their senses, of course.  Not with some mysterious power.  Granted, this power may seem mysterious to those who don't have or understand it.  But they use their sense of smell. 
I have been able to "sense" when someone has a sinus infection before.  How?  By smell.  Your air smells different.  Granted, most people won't pay attention to something like that, or really think about it if they did.  The amazing senses we have been given are everyday tools but also subconscious detection tools.  We just don't always pay full attention to them due to our busy days and lives and minds.  We must take time to clear our minds and focus in order to develop sharper senses.
