Mark 6:52 for they had not understood about the loaves; their hearts were hardened.

John 10: 28 I give them eternal life, and they shall never perish; no one will snatch them out of my hand. 38 But if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me, and I in the Father.”

Romans 8:32 32 He who did not spare His own Son, but delivered Him over for us all, how will He not also with Him freely give us all things?
