Yes, just as Jesus told the Apostles.
Baptizing them in the
Name of the Father - GOD
and of the Son - GOD
and of the Holy Spirit - GOD

The triune nature of God is manifest throughout
the scriptures from Genesis to Revelation.

There is ONE GOD, and He has a triune nature.

What is GOD?

The Father, and the Son, and the Holy Spirit.

Before Jesus stepped off the throne of Heaven
and became flesh, GOD existed eternally as:

The Father, and the Word, and the Holy Spirit.

In God's dealing's with man, the Word of God appears
many times as an angel.
He appeared to Moses and spoke to him face to face.
He walked with the three Hebrew children in the
fiery furnace. He appeared in Daniel's visions.

To Isaiah he is referred to as the ARM of the Lord.

Jesus rebuked those who couldn't see Him in Scripture:

JOHN 5
36 But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.

37 And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.

38 And ye have not his word abiding in you: for whom he hath sent, him ye believe not.

39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.

40 And ye will not come to me, that ye might have life.

He created eveything that IS, He told Moses His name,
I AM.
I AM is His name.
He came to save his creation, and to those who
come to Him, He will grant eternal life.
