A person or a vessel sanctified is SET APART TO GOD absolutely and perfectly. "By the which will we are sanctified through the offering of the body of Jesus Christ." Heb. 10:1010By the which will we are sanctified through the offering of the body of Jesus Christ once for all. (Hebrews 10:10).
This is our position always before God as the fruit of the work of Christ upon the cross. This is "positional sanctification" and never changes.
To sanctify the Lord of Hosts is to have Him before us to the exclusion of all others, so that we give Him credit for all that He is as He has revealed Himself to us-see Isa. 8:1313Sanctify the Lord of hosts himself; and let him be your fear, and let him be your dread. (Isaiah 8:13).
In the poem following, note stanza 3. It says each is "meet"-that is, positionally sanctified-and "training"-that is, progressive sanctification, which is the practical application of the truth to our daily lives.
Every believer is "positionally sanctified."
O GOD of grace, our Father,
All praise we give to Thee,
'Tis in Thy sovereign favor
All blessedness we see;
There only is the fountain
Whence living waters flow,
Which like a glorious river
Still gladden as they go.
As Thine, Thou didst foreknow us
From all eternity;
Thy chosen loved ones ever,
Kept present to Thine eye;
And when was come the moment,
Thou, calling by Thy grace,
Didst gently, firmly draw us
Each from his hiding-place.
Thy Word, Thyself reflecting,
Doth sanctify by truth,
Still leading on Thy children
With gentle heavenly growth.
Thus still the work proceedeth,
The work begun by grace,
For each is meet, and training,
Father, to see Thy face.
