A quote from Biblereader -
27: My sheep hear my voice, and I know them, and they follow me:
28: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29: My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30: I and my Father are one. (John 10.27-30)
But, that brings this up, which I believe: no man is able to pluck the saved out of God's hand.
We are secure in our salvation.
We might, and will, sin, after salvation, but we REPENT, and change our course.
We stay on the straight and narrow.
I think that you may have misapplied some context here!
As I see things, Jesus offers some clarity on His statement above, here...
John 17:12 KJV
(12) While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.
And, also, here...
John 18:8-9 KJV
(8) Jesus answered, I have told you that I am he: if therefore ye seek me, let these go their way:
(9) That the saying might be fulfilled, which he spake, Of them which thou gavest me have I lost none.
Clearly, Jesus was not talking about ALL Christians in these passages, but the apostles only.
John 10:16 KJV
(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.
And, as I see it, the context applies only to the physical safety of the apostles themselves, while Christ was still walking on this earth. Because, once Christ had been crucified, all manner of harm, torture, and death were suffered by these chosen ones.
Biblereader, I repeat, as I see it, the passage which you reference above is only talking about one of the many folds of sheep which make up God's flock, His apostles.
May God bless us all,
