The context concerns his disciples. His messengers when he was on earth
That does not mean there cannot be an extended application
Again you have posted nothing which speaks of unconditional election
His disciples were given to him by the Father to whom they belonged
John 17:1–8 (ESV) — 1 When Jesus had spoken these words, he lifted up his eyes to heaven, and said, “Father, the hour has come; glorify your Son that the Son may glorify you, 2 since you have given him authority over all flesh, to give eternal life to all whom you have given him. 3 And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent. 4 I glorified you on earth, having accomplished the work that you gave me to do. 5 And now, Father, glorify me in your own presence with the glory that I had with you before the world existed. 6 “I have manifested your name to the people whom you gave me out of the world. Yours they were, and you gave them to me, and they have kept your word. 7 Now they know that everything that you have given me is from you. 8 For I have given them the words that you gave me, and they have received them and have come to know in truth that I came from you; and they have believed that you sent me.
Christ is speaking to every Christian to take the message of Christ's salvation to all.
You conveyed "The context concerns [exclusively] his disciples. His messengers when he was [only] on earth" respecting John 15:16-19, yet you contradict yourself in your self-will because you reviled these angelic majesties by effectively labeling the Apostles as deceivers with your unretracted previous writing of "Nothing mentioned about Joseph and Matthias being in the audience on that ocassion" of which your thoughts there daringly contradict angelic majesties testimony of the Apostle Peter "men who have accompanied us all the time" (Acts 1:21) while he was with all the Apostles.
Joseph and Matthias were in the room when Lord Jesus says "you did not choose Me, but I chose you" (John 15:16) and "I chose you out of the world" (John 15:19, includes salvation).
So, you call the Apostles all liars because all the remaining Apostles were with the Apostle Peter when Peter said:
Therefore it is necessary that of the men who have accompanied us all the time that the Lord Jesus went in and out among us - beginning with the baptism of John until the day that He was taken up from us - one of these [must] become a witness with us of His resurrection.' So they put forward two men, Joseph called Barsabbas (who was also called Justus), and Matthias.
(Acts 1:21-23)
Thus, Matthias and Joseph are at least two more people beyond the Apostles for a minimum total of 13 disciples who are specifically identified at the supper covered in John chapters 13-17; therefore, Lord Jesus Christ's "you" in John 15:16 and John 15:19 extends well beyond the Apostles, in Truth (John 14:6)!
Based on your writing above, you cannot be Jesus Christ's friend despite your "Yes" to the question "Do you think you are a friend of Jesus, TomL?" because you express conflicted thoughts about the population of Christ's "you" in the passage. I remind you for this exchange that I consider you to write "apostles" whenever you write "disciples".
Let's take a look at Lord Jesus Christ's usage of "you" with which the above question and answer pertains:
I have called you friends, for all things that I have heard from My Father I have made known to you. You did not choose Me but I chose you
(John 15:15-16 (you replied to a fully quoted John 15:14-19 (links to KJV, NASB1995, and YLT)))
Your response of "Yes" shows your personal claim of being part of the "you" population inside of God's blessing of "I have called you friends" (John 15:15), but then in the continuation of the very same blessing, your heart's "it was Christ words [exclusively] to the disciples messengers he had chosen" eliminates you, TomL, from being a part of the "you" population inside of God's blessing of "I chose you" (John 15:16); therefore, you are not a chosen friend of Jesus according to your own self-willed heart's treasure which leavens your whole loaf of free-willian philosophy (Matthew 16:6).
In effect, your "Yes" and "it was Christ words [exclusively] to the disciples messengers he had chosen" expresses a confused (1 Corinthians 14:33) "Yes No" concept about the audience represented in Christ's "you" recorded in John 15:14-19.
You wrote "Nothing there concerning on what basis he chose them" which conveys your thoughts that, somehow, the Apostles chose Jesus thus your purported choice executed by the Apostle's is your purported "basis" for Jesus choosing the Apostles, yet every Christian's Lord Jesus Christ says "you did not choose Me" (John 15:16), so God eliminates any purported free-will choosing by man towards God; therefore, your "basis" conjecture provides only shifting sand diversion away from the Truth (John 14:6) for you.
King Jesus decrees over the Kingdom of God:
- "you did not choose Me, but I chose you" (Lord Jesus Christ, John 15:16), so God chooses people to be friends (John 15:15, the prior verse) and to believe (John 6:29) and to be born again (John 3:3-8) and for righteous works (John 3:21, John 15:5) and to repent (Matthew 11:25) and to love (John 13:34) and unto salvation (John 15:19 the same passage).
- "I chose you out of the world" (Lord Jesus Christ, John 15:19, includes salvation), so God exclusively chooses people unto salvation.
- "What I say to you I say to all" (Lord Jesus Christ, Mark 13:37 - Jesus had taken the Apostles Peter, Andrew, James, and John aside in private and said this), so all the blessings of God mentioned above are to all believers in all time.
The only way for free-willian philosophers to acheive free-will is for them to add to the Word of God, and it is written "do not add to His words or He will reprove you, and you will be proved a liar" (Proverbs 30:6).
No Holy Scripture states man has a free-will.
Every person has a will, but a person's will is either one of but not both of (1) a self-will against God in evil for the natural flesh person (2 Peter 2:9-10) or (2) a will in Christ doing God's good by the Holy Spirit for the Born of God (Romans 8:29, Philippians 2:13, John 3:3-8).
