How do the following verses in Jesus' high-priestly prayer reveal that His saving love and work was for His saved Church, but not for the world at large?
I pray for them: I pray not for the world, but for them which Thou hast given Me; for they are Thine.
And all Mine are Thine, and Thine are Mine; and I am glorified in them.
Father, I will that they also, whom Thou hast given Me, be with Me where I am; that they may behold My glory, which Thou hast given me: for Thou lovedst Me before the foundation of the world.
0 righteous Father, the world hath not known Thee: but I have known Thee, and these have known that Thou hast sent Me.
-John 17:9-10, 24-25
1. Christ died in a saving way only for His chosen people (not "for all," as Arminianism proclaims).
And she shall bring forth a son, and thou shalt call His Name JESUS: for He shall save His people from their sins.
Even as the Son of man came not to be ministered unto, but to minister, and to give His life a ransom for many.
For this is My blood of the New Testament, which is shed for many for the remission of sins.
Husbands, love your wives, even as Christ also loved the Church, and gave Himself for it;
That He might sanctify and cleanse it with the washing of water by the Word.
I am the good Shepherd, and know My sheep, and am known of Mine. As the Father knoweth Me, even so know I the Father: and I lay down My life for the sheep.
So Christ was once offered to bear the sins of many; and unto them that look for Him shall He appear the second time without sin unto salvation.
2. Christ's death secured the full salvation of the elect (not
"only opened a possibility for it").
For the Son of man is come to seek and to save that which was lost.
Grace be to you and peace from God the Father, and from our Lord Jesus Christ,
Who gave Himself for our sins, that He might deliver us from this present evil world, according to the will of God and our Father.
For if, when we were enemies, we were reconciled to God by the death of His Son, much more, being reconciled, we shall be saved by His life.
This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.
-I Timothy 1:15
Who gave Himself for us, that He might redeem us from all iniquity, and purify unto Himself a peculiar people, zealous of good works.
And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath He reconciled In the body of His flesh through death, to present you holy and unblameable and unreproveable in His sight.
3. Christ's redeeming work is always effective due to the Spirit's irresistible application of it to the elect (not "uncertain due to the Spirit being dependent upon a person's prior choice to accept God's salvation").
