There is One Lord Eph 4:5 Deu 6:4.
His name is Jesus

Jesus is the BodyOfGod. -> He is not with us -> He is in heaven.

The HolySpirit is the SpiritOfGod. -> He fills the universe. -> He is in us and we are in Him. -> He is the one who speaks to us -> He is the one who guides us -> He is the one who empowers us. -> He is the one who speaks through us.

The HolySpirit is the SpiritOfChrist Jesus.

When we are saved we receive the HolySpirit in the name of Jesus.
