John 8:50-52

50 However, I am not in search of honor for Myself. [I do not seek and am not aiming for My own glory.] There is One Who [looks after that; He] seeks [My glory], and He is the Judge.

51 I assure you, most solemnly I tell you, if anyone observes My teaching [lives in accordance with My message, keeps My word], he will by no means ever see and experience death.

52 The Jews said to Him, Now we know that You are under the power of a demon ([4]insane). Abraham died, and also the prophets, yet You say, If a man keeps My word, he will never taste of death into all eternity.
