Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me. (Psalm 23:4 KJV)

For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep. (1 Thessalonians 4:14)

I give them eternal life, and they will never perish, and no one will snatch them out of my hand. (John 10:28)
