Understanding Salvation; Justification from Past Sins unto Righteousness, and Sanctification from Present Sins unto Holiness: The Ministry of Jesus as our PROPITIATION And ADVOCATE.
In the first two verses of 1 John 2, two words are used in relation to the Lord
1 John 2:1
My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.
1 John 2:2
And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
Propitiation (in verse 2), and Advocate (in verse 1).
They are NOT the same word.
As the Propitiation, Jesus is the Atonement Lamb, the Sacrifice; But as the Advocate, He is the High Priest.
He died as the Atonement Lamb, but He was raised as the Advocating High Priest
The Lamb took away the sins of the whole world, so Propitiation is for all men, including all saints; but High Priest is the Advocate with the Father only for the Church.
As the Atonement Lamb, He is the Savior of the world; but as the Advocating High Priest, He is the Savior of the Body
As the Atonement Lamb, Jesus became sin, died and went to hell; that all men might be justified; but concerning the High Priesthood, He is sinless, He lives and has ascended; that those who have been justified might be sanctified and glorified.
As the Atonement, Jesus became the last Adam; but concerning the High Priesthood, He is the Second Man.
The Atonement pertains to the old covenant; the High Priesthood pertains to the new covenant
The Atonement brings to an end all that is of the old creation; the High Priesthood is for the perfecting of all that is of the new creation.
The Atonement or Propitiation is for sins committed in the old life; and under the old covenant for those who were under it, because the blood of bulls and goats in that covenant could not take away those sins.
But the High Priesthood is for sanctification, cleansing and purifying in the new covenant for those who have new life.
So the Propitiation is for justification from past sins, but having been justified, if any one in the church sins, the Advocating High Priesthood deals with that.
We are saved from the world into the church, through the Sacrifice of Jesus; but we are being kept through faith unto salvation ready to be revealed in the last day, through the High Priesthood of Jesus.
The Atonement brings justification unto righteousness; the High Priesthood brings sanctification unto holiness.
Therefore, for the unbeliever, Jesus has taken care of their sins as the Lamb, the sacrifice. He is not their Advocate. He cannot advocate anything for them. He cannot sanctify them. What they need is to accept that sacrifice by believing in Him. So they may be justified. That’s what propitiation is for.
When an unbeliever has done that and believed. All his sins are forgiven and he has been brought into a new covenant with the High Priest who is His advocate, fully justified.
Old things pass away and all things become new
The one who justified him from all things past including his PAST SINS, (those committed under the old covenant or in the old life as in the case of non-Jews who were never under the old covenant.)……NOW SANCTIFIES HIM as the High Priest or advocate before God, by the blood of sprinkling.
For the believer, he is both the Atonement or Propitiation that dealt with the old life and the and the Advocate that is the Apostle of his new life and the High Priest of the new covenant
Jesus died to save the world, but He lives only for His Church.
As the Atonement Lamb, God was in Christ reconciling the world to Himself; but as the High Priest, Christ stands before God for those who have been reconciled, preparing a people for Himself.
The Atonement came by the obedience of one Man, but the High Priesthood is for all those who having been justified by His obedience, now in turn obey Him.
Therefore Jesus came to the world and died for all men, but He is High Priest only for those who come to Him. They are ones who by that coming are perfected forever by that one Sacrifice, being sanctified.
As the Atonement Lamb, Jesus came for a sinful world; but concerning the Advocating Priesthood, He is coming for a sinless church.
