There is no Bible text stating that "Yahushua is God" or Yahushua is "God the Son". To find out if Yahushua is God or not, we have to identify, who God is first:
1Ti 1:17 Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
1Ti 6:16 Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.
Our only true God is:
1) eternal
2) Immortal
3) invisible to any man
4) dwelling in the light which no man can approach
If Yahushua was eternal, immortal, invisible, we could consider him to be God. Let us check:
1) Was Yahushua eternal? No, he was born of Mary:
Mat 1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
Luk 2:7 And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.
Gal 4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law...
2) Was Yahushua immortal? No, he died on the cross and was raised from the dead:
Joh 19:30 When Yahushua therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost.
1Pe 3:18 For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
Php 2:8 he humbled himself by being fully obedient to God, even when that caused his death--death on a cross.
Php 2:9 So God raised him up to the most important place and gave him the name that is greater than any other name.
3) Was Yahushua invisible? No, he was visible, before and after his resurrection:
Mat 2:11 The wise men came to the house where the child was with his mother Mary. They bowed down and worshiped him. Then they opened the boxes of gifts they had brought for him. They gave him treasures of gold, frankincense, and myrrh.
Mat 5:1-2 When Yahushua saw the crowds of people there, he went up on a hill and sat down. His followers came and sat next to him. Then Yahushua began teaching the people.
Mar 16:9 Now when Yahushua was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils.
Mar 16:12 After that he appeared in another form unto two of them, as they walked, and went into the country.
Mar 16:14 Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen.
4) Is Yahushua dwelling in the light which no man can approach? No, he was seen by others:
Luk 9:1 Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases.
Joh 4:7 There cometh a woman of Samaria to draw water: Yahushua saith unto her, Give me to drink.
Conclusion: Because our Bible never says "Yahushua is God" or "Yahushua is God the Son" and because Yahushua was not eternal, immortal, or invisible, Yahushua is not God. There is only one true God, the Father Yahuwah.
