God is Jesus or Yahweh

The Word "god" means any deity of any religion. Because Judaism and Christianity recognize only one god, the Word became used as the name of the god: God.

The name YHWH is the sacred name by which the Hebrew people knew their god. The name was so sacred that devout Jews never spoke it aloud, but substituted other Words meaning The Lord.

In the Christian faith, Jesus Christ is recognized as the Son of God, born of the Virgin Mary. This means that the Jewish God, YHWH, is the Father of Jesus Christ.

In the 3rd Century, the Church struggled to understand and explain exactly the question you have asked. At the Council of Nicea, from which came the Nicean Creed, the leaders of the church decided that the answer is "Yes!" Jesus is God, and the Father (YHWH) is God, and the Holy Spirit is God. This is known as the Trinity: One God in three Persons.
