No! "Jesus IS God!" is one of the most false, deceptive and demonic doctrines taught among many Christian religions.

As for all being sons and daughters of Father Yahweh ["God"], this is not true, since it says in Father Yahweh's inspired word:

"That is, They which are the children of the flesh, these [are] not the children of Yahweh: but the children of the promise are counted for the seed (Romans 9:8)."

It is clear here that there are "children of the flesh" who are not children of Father Yahweh.

"For you are all the children of Yahweh by belief in Messiah Yahshua (Galatians 3:26)." One must have Yahshua as their brother (Acts 7:37, 8:17).

It is clear here that if one does have belief in Yahshua Messiah that they are not children of Father Yahweh.

"Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to [our] father: for I say unto you, That Yahweh is able of these stones to raise up children unto Abraham (Luke 3:8)."

It is clear here that if one does not bring forth fruits worthy of repentance one is not a child of Father Yahweh. Note to have father Abraham {"children of the promise" [of Abraham's seed] as your father is to be a child of Yahweh (Romans 9:8; Acts 3:25, 13:26).

"Let no man deceive you with vain words: for because of these things comes the wrath of Yahweh upon the children of disobedience (Ephesians 5:6)."

It is clear here that the "children of disobedience" are not the children of Yahweh (Also cf. Colossians 3:6).
