Word makes everything possible but as you sow you reap every word is a seed that grows when planted in the mind. God is everyone of them seeds.Matter and energy do speak if it was  not for the words you could never know matter or energy existed. The knowledge of them is in the words that make them. 

You do all you can to know God, through his Holy Church, his written Word, his Sacraments and his prayerful devotions.

Not for me.  There never was, isn't & never will be any "God".  That's a fiction created 100's of years ago by someone in a failed effort to understand things that may well be outside the range of human epistemology.  

It can be pretty difficult.  One way of telling is if you hear something you would not think of yourself.  E.g., like doing something difficult to return to the correct path.  Also, God resonates with all that has happened before.  If you hear instructions for doing something that God would not say - it isn't God.

The voice of God is more like a critic and tends to say things you don't want to hear.

If you have learning problems, if you read Holy Scripture, and sometimes you can't quite understand its meaning, we have our Bible schools open, twice a week, to give explanations about many questions asked by the new, sympathetic people?

1) When a true Christian prays to God, he knows how to distinguish his voice, because he is powerful, he is sweet, and, penetrating the soul, it is impossible to describe it in every sense.For when one prays to God, it is He who intercedes!!!

2) If instead any person is far from God, and hears voices inside his mind and soul, those voices are demons! That is where the difference is, it is impossible not to recognize the difference.

Revelation 21:3.

Then I heard a powerful voice coming out of the throne:"Behold the dwelling place of God with men!He will dwell among themand they will be his peopleand he will be the "God-with-them".4 And he will wipe every tear from their eyes;there will be no more death,neither mourning, nor moaning, nor breathlessness,because the things of before are past".

Joel 2:11.

The LORD makes his voice heard before his army,because his ranks are countless, because the executor of his word is powerful.

Psalm 29:4.

The voice of the LORD is mighty, the voice of the LORD is full of majesty.

When I hear from God the Holy Spirit It feels like it comes from inside of me from the center, definitely not from the head.

There is no internal "voice of God" (or even external for that matter).

When God directly talks to someone, by definition, that makes them a prophet, and all that ended long ago (1Cor 13:8-10).  Here's another way we know.

God used miracles with his prophets to confirm to their listeners that their words were God's words (Ex 4:1-9; 7:8-10; Jn 3:2; Mk 16:17-20; Ac 8:6; Heb 2:3-4).  So for example, if someone claims that God spoke them, but won't drink a bottle of Clorox bleach (without it harming them) to prove it, they're just lying to you.  Since God's word was confirmed long ago (into what we today call the New Testament), such miracles are no longer needed.

There is no god.

Stop acting like

a stupid child.

'God' is a man made myth.  Your inner voice doesn't actually speak aloud, it's inside your head.
