For there are three that bear record in heaven,
the Father,
the Word,
and the Holy Ghost:
and these three are one.
And there are three that bear witness in earth,
the Spirit,
and the water,
and the blood:
and these three agree in one.
1 John 5:7,8
Analysis in light of the Sanctuary:
* The Trinity/Godhead gives themselves a role in each compartment:
Outer Court (Justification) the Son
Inner Court (Sanctification) the Spirit
The Most Holy Place (Glorification if one passes their judgment) the Father
* The plan of Redemption is the outer/inner court that one must pass through before the Judgment in the Most Holy Place. So all 3 have a part in the Justification/Sanctification
process as well if we look closer in detail.
1) Outer Court
a) The Son with His blood sacrifice upon the altar
b) God the Father as the Water which washes away symbolically sin / brazen laver. He is the one who will use the blood of Christ in the judgment to blot out your sin (wash them away).
2) Inner Court
c) The Spirit through Sanctification (the furniture representing a changed life - altar of incense/prayer, table of bread/study of His Word & 7 branch candlestick/witnessing).
Even here we see more detail in the Inner Court. For here are 3 articles of furniture giving each an even more detailed role. Altar of Incense = Prayer to the Father.... Table of Bread is not just the Bread of His Word, but Christ also referred to himself as the Bread of Life....And then the 7 Branch Candlestick of witnessing by the oil of the Holy Spirit.
