John 5:24, 6:47. 54; 1 John 5:11

Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.

Truly, truly, I say to you, whoever believes has eternal life.

Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day.

And this is the testimony, that God gave us eternal life, and this life is in his Son. (ESV)
