My Sheep Listen to My Voice (John 10:27-29)

My sheep listen to my voice; I know them, and they follow me. I give them eternal life, and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all. No one can snatch them out of my Father's hand. I and my Father are one.

Who says Jesus never claimed to be God? See also John 14:6-11

Who says we can lose our salvation? Who or what can snatch us out of God's hand?
