Passage
That which my Father hath given me is greater than all: and no one can snatch them out of the hand of my Father.
That which my Father hath given me is greater than all: and no one can snatch them out of the hand of my Father.
John 10:27 My sheep hear my voice. And I know them: and they follow me.
John 10:28 And I give them life everlasting: and they shall not perish for ever. And no man shall pluck them out of my hand.
John 10:29 That which my Father hath given me is greater than all: and no one can snatch them out of the hand of my Father.
John 10:30 I and the Father are one.
John 10:31 The Jews then took up stones to stone him.
The verse centers on "father", "hath", "given", "greater", "than", "snatch", and "hand". It is saying that the verse draws attention to "father" and "hath", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "And I give them life everlasting and..." into verse 30's "I and the Father are one...", so "father" and "hath" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "father" and "hath" with trust shaped by these words, not by a vague optimism outside the passage.
