John 6:33
For the bread God gives is the One [see verse 35] who comes down from heaven, and [He] gives [spiritual] life to the world."
John 6:35
Jesus replied, "I am the bread who gives [spiritual] life; the person who comes to me will never get hungry [again], and the one who believes in me will never get thirsty [again].
John 6:51
I am the living bread who came down from heaven; if anyone eats this bread, he will live forever. Yes, and the bread that I will give [him] is my physical body, [so] that the world can have [never ending] life."
John 6:53-56
So, Jesus answered them, "Truly, truly, I tell you, unless you eat the physical body of the Son of man and drink His blood, you do not have [spiritual] life in yourselves [Note: The references to "body" and "blood" throughout this section allude to taking Jesus' life and teaching into one's heart. See verse 56].
Galatians 2:20
I have been crucified [i.e., died] with Christ, and so I am not the one who lives [anymore] but rather, it is Christ who lives in my heart. And [now] my entire life is being lived by trusting in the Son of God [to save and keep me], because He loved me and gave Himself up for me.
