The Gospel also is for the future sheep, they hear this message of being in the vine and understand that occured when Jesus gave the Holy Spirit, for us all to be one in Him, nothing perfect came before then..
John 10:16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
Here is the question for you guys, in your own minds, Jesus had to sanctify Himself, for the disciples sakes, and to make all perfect in one, Him in them and them in Him.
Do you think they are in Him ( Christ) already and perfect ( the disciples with Jesus) or they needed the death and rising of Christ?
John 17:19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.
John 17:23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
Jesus became High Priest, by replacing the old covenant that brought death which then brings us near to Christ to make them perfect....
Hebrews 7:17 For he testifieth, Thou art a priest for ever after the order of Melchisedec.
18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof.
19 For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God.
This man ( Jesus Christ) offered Himself as sacrifice, and by that one offering He perfected for ever them that are sanctified ( Jesus sanctified Himself in the death of the cross to sanctify the disciples)
Do you say that the disciples were sanctified before Christ was dead and risen ?
It makes no sense if you say yes.
As Jesus first had to be sanctified, then to sanctify the disciples through the truth ( through the Spirit of truth then given to them) and the one offering HE PERFECTS FOREVER THEM THAT ARE SANCTIFIED..
Hebrews 10:12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
13 From henceforth expecting till his enemies be made his footstool.
14 For by one offering he hath perfected for ever them that are sanctified.
John 17:19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.
This gives the new covenant, ( Christ had to do this to take the curse away which the disciples were still under as it is only nailed on His cross.)
Jesus then by giving the living Holy Spirit of Christ into all ( only after He died and rose) gives all then the new living way, this is by the blood of Jesus, and without shedding of blood here is no remission, and then no faith even for the disciples of Christ but we receive the promise of the Spirit through faith ( the faith of Christ to die for us which through the faith of Christ we believe in that righteousness of God)..
Hebrews 10:16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
17 And their sins and iniquities will I remember no more.
18 Now where remission of these is, there is no more offering for sin.
19 Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,
20 By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
Galatians 3:13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:
14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
