how God reveals himself to different people in all world?

There is ONLY ONE TRUE AND ETERNAL GOD.

well, first of all "God" does not reveal himself to just "anyone". God speaks to JESUS and jesus manifests himself to men.

usually such manifestations are only given to prophets, to those that are faithful and holy, and to those that love the commandments and are repentant.

when a person is faithful unto jesus, HE said he would show the Father. HE never did say HE was the Father. !

so if someone sees a dream, it could be a false witness. or an imagined vanity. but the Lord did communicate to Daniel in his dreams. this is indisputable. . however it is proveable that not all dreams of jesus are really jesus, and not all voices heard are the voice of God, or even the holy ghost. knowing that sometimes even angels will appear and speak, sometimes even with voices of thunder.

We have the same God:)

Allah is God. The name Allah is the Arabic word for God. More precisely, it is the One Eternal Creator, Lord of the whole universe. It is the same Arabic name for God that is used in the Arabic Bible.

It is pronounced almost the same in other Semitic languages: "Eloha" in Hebrew, and "Allaha" in Aramaic. According to Jesus (peace be upon him), God is One, with no partner whatsoever. I quote the following verses from the Bible:

Jesus said to him, "Away from me, Satan! For it is written: 'Worship the Lord your God, and him only.'" (Matthew 4:10)

"Well said, teacher," the man replied. "You are right in saying that God is one and there is no other but him." (Mark 12:32)

Allah is mentioned by Name in Hindu Scriptures

The Word “Allah”, which refers to Almighty God in Arabic, is also mentioned in

Rigveda Book 2 hymn 1 verse 11

Rigveda Book 3 hymn 30 verse 10

Rigveda Book 9 hymn 67 verse 30

There is an Upanishad by the name ALO Upanishad.

How about revealing himself the way real things do, by just showing up. Making a sound. Knocking on a door.

Don't make up stuff.
