John 10 is being used to deceive the sheep — many ‘pastors’ today lying by omission. This first part of the passage (v. 27) is rarely quoted when they claim Jesus is saying we cannot lose our salvation. Jesus’ sheep hear His voice and follow Him, and no one can snatch them out of Jesus’ hand.
27 My sheep hear my voice, and I know them, and they follow me. 28 I give eternal life to them. They will never perish, and no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all. No one is able to snatch them out of my Father’s hand.
Who is “them?” Those who hear Jesus’ voice and follow Him.
Then look at what Jesus says in John 15 about the Vine and the branches. Branches that don’t abide in Him, not producing fruit that remains are cut off, thrown into the fire and burned.
We must hear and obey to be Jesus’ sheep.
