Your breath is not a separate person from you, just as your body is not a separate person from your mind.
And we're not God. . .they are separate when they are God's. . . as clearly seen in the OT,
previousy addressed, following:
God's Word is his almighty breath (spirit),
and
in the OT, his Word and his Spirit are parallel figures.
The speech (Word)
and breath (Spirit)
of God appear in creation (Ge 1:2ff, Ps 33:6).
The NT reveals that the divine Word of Ge 1:3, 9, 24, Ps 33:6, 9; Is 55:11
is a person (Jn 1:1-18).
Jesus teaches that the divine Spirit (breath) of Ge 1:2; Job 26:13, 312:8, 33:4, 34:14-15, Ps 33:6
is a person
(see Jn 20:22, and Ac 2:2 where God's Spirit (breath)--is as the blowing of a mighty wind).
Jesus teaches the deity of the personal Holy Spirit by calling him the "holy" Spirit,
just as he spoke of the "holy" Father (Jn 17:11).
Holy was the OT adjective for expressing the God-ness of God,
as Lord was the Greek OT name and title denoting the Godhood of God.
And just as the name and title,
Lord,
of the Greek OT is used in the NT chiefly not of the Father,
but
of the Son;
so the adjective,
holy, is mainly applied in the NT, not to the Father, but
to the Spirit.
The NT reveals that the Son is God, and the Holy Spirit is likewise God,
both separate persons from God the Father (Mt 3:16-17, 28:19).
