Can Jesus loose what He found ?
If one Christ saved, having apprehended that one as per
Phil 3:12
12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also
I am apprehended of Christ Jesus.
The word apprehended is the greek word katalambanō:
to lay hold of, find
a) to lay hold of so as to make one's own, to obtain, attain to, to make one's own, to take into one's self, appropriate
For that one He did apprehend to become lost again means He lost what He had or apprehended, that is His fault.
For Christ as the Shepherd of the Sheep He finds or apprehends is responsible for them.
Lk 19:10
10 For the Son of man is come
to seek and to save that which was lost.
Now once the Shepherd finds the Lost Sheep as here
Lk 15:5
5 And when he hath
found it, he
layeth it on his shoulders, rejoicing.
Laying it upon His Shoulders denoting His Strength and protection of the found Sheep, also acknowledging the weakness of the sheep, it also denotes His Responsibility for the Sheep now to be under His Care and Protection.
In light of this Jesus speaks of the Security of the found Sheep
Jn 10:27-30
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.
Jesus here speaking as the Good Shepherd of the Sheep, ensures the Security of the Sheep and says they are safe in His Hands, and they cannot be plucked out of His Hands !
This promise goes back to
Jn 10:4-5
4 And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.
5
And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
