Because the Gentiles "accepted" the Message, by doing so, they "enrolled themselves", but only because they are responding to the inward call of the Holy Spirit. You have misunderstood the Greek grammar here, and used "theology" to determine what it sould be.
To me, they did so because they were ordained to eternal life by the Lord Himself.
Again, "passive voice".
People "receive Christ" ( John 1:11-13 ) because God the Father
gave a people to His Son...
Not because we "reached out" and took it of our own volition or because we somehow "met God halfway" by our belief of His words and by "enrolling ourselves" into His kingdom...
He is the one who enrolled those that would someday believe on His Son:
Known unto Him are all His works ( Acts of the Apostles 15:18 ) which were finished from the foundation of the world ( Hebrews 4:3 ).
Again, Acts of the Apostles 13:48, and we can then add Romans 8:28-30, Ephesians 1:3-11, 2 Thessalonians 2:13-14 and several others;
Including John 6:37-68.
We find this proof that it is
God alone that saves according to His grace sprinkled throughout God's word...
That He does the choosing, and causing a person to approach unto Him ( Psalms 65:4 ).
That cause is the inward call of the Holy Spirit to one of God's precious children ( 1 Corinthians 1:9 ).
They come when they are called because it is given to them to know the mysteries of the kingdom of God ( Matthew 13:10-12 ), because they have ears to hear ( Matthew 11:15, John 8:43-47, Revelation 3:13, Revelation 3:22 ), because they are His sheep and have been given eternal life ( John 3:36, John 5:24, John 10:26-27 ) and because they were given to Him by His Father ( John 6:37, John 6:44, John 6:65, John 17:2 ).
He did all this for His great love wherewith He loved them, even when they were dead in trespasses and sins ( Ephesians 2:1-6 ).
They are vessels of mercy which He has afore prepared unto glory ( Romans 9:23-24 ) and His workmanship, created "in Christ Jesus" ( Ephesians 2:10 ) for one specific purpose...
To the praise of the glory of His grace ( Ephesians 1:6 ).
Respectfully,
I don't need to fully understand Koine Greek, as the Lord has preserved His word for me to examine for myself in my own language.
I understand English grammar, and I take my "theology"
out of God's word.
To clarify and in case there is any doubt as to why I hold to what I do:
I do not read the writings of men who have come before me, and then take their conclusions and commentaries and read those understandings
back into the Bible.
Some may do that, but I do not.
I see "unconditional election" and many other truths by carefully reading and believing the words on the page...and in cases where I do not, I continue my studies and leave it to the Lord to show me the correct understanding of something;
Not by reading along, finding something I don't understand, and then searching for an explanation for it
outside of the Bible like many seem to have done in the past and are doing these days.
I also clearly see that God does not ordain men to sin, because His word tells me point-blank that He does not condone it.
In the end, God is sovereign when it comes to salvation and men are responsible to repent and believe on His Son...
Though they will not ever do it apart from the work of the Holy Ghost in them.
I wish you well and much profit in your studies of His word...
This is my final reply in this thread.
May He someday reveal to you, in every detail, what he has done through the Gospel and through His Son for the sake of His precious children...
For it is these details that develop the how and why any of us are saved from His coming wrath and judgment.
These details make Him worthy of
every bit of the fruit of our lips...
For we will praise Him for His grace and our salvation for all eternity.
