John 12:24

12:24 I tell you the solemn truth, unless a kernel of wheat falls into the ground and dies, it remains by itself alone. But if it dies, it produces much grain.

John 15:4-5

15:4 Remain in me, and I will remain in you. Just as the branch cannot bear fruit by itself, unless it remains in the vine, so neither can you unless you remain in me.

15:5 “I am the vine; you are the branches. The one who remains in me – and I in him – bears much fruit, because apart from me you can accomplish nothing.

John 21:18

21:18 I tell you the solemn truth, when you were young, you tied your clothes around you and went wherever you wanted, but when you are old, you will stretch out your hands, and others will tie you up and bring you where you do not want to go.”
