What's a god?

That is the primary question, and no religionist goes into great
details about his god, but all religions feature some definition. One's
god is always something that is exceedingly important. It's the focus of
one's life. Most people's god is Mammon, who represents the lust, or greed
for money.
Our Christian God is both knowable and visible. See below Christ
explaining His God to a skeptical Philip.

"GOD" THE CHRISTIAN MEANING OF THE WORD ACCORDING TO SCRIPTURE:
Jesus in Jn:4:24: "GOD IS A SPIRIT, and they that worship him must
worship him in spirit and in truth."
Jesus in John 14:6-10: Jesus saith unto him: "I am the way, the truth,
and the life; no man cometh unto the Father, but by me. If ye had known
me,
ye should have known my Father also, and from henceforth YE KNOW HIM AND
HAVE SEEN HIM."
Philip saith unto him: "Lord, show us the Father, and it sufficeth us."
Jesus saith unto him: "Have I been so long time with you, and yet hast
thou not known me, Philip? HE THAT HAS SEEN ME HATH SEEN THE FATHER;
and how sayest thou then: Show us the Father? Believest thou not that I am
in the Father, and the Father in me? The words that I speak unto you I
speak
not of myself, but the Father that dwelleth in me, he doeth the works."
Jesus in John 12:44-46`Then Jesus cried out and said, "He who believes
in me, believes not in me but in Him who sent me. And he who sees me sees
Him who sent Me. I have come as a light into the world, that whoever
believes in me should not abide in darkness."
Jesus in Lk 17:20-21: And when he was demanded of the Pharisees, when
the kingdom of God should come, he answered them and said: "The kingdom of
God cometh not with observation. Neither shall they say, Lo here! or, lo
there! For, behold, the kingdom of GOD IS WITHIN YOU."
1Jn:4:8: He that loveth not, knoweth not God; for GOD IS LOVE.
1Jn:4:16: And we have known and believed the love that God hath to us.
GOD IS LOVE; and he that dwelleth in love dwelleth in God, and God in him.
Acts:17:28: For in him we live, and move, and have our being; as
certain
also of your own poets have said, For we are also his offspring.
