John 6:56

The one who eats ¹  my flesh and drinks my blood resides in me, and I in him. ² 

Ps 90:1; Ps 91:1,9; La 3:24; Joh 14:20,23; Joh 15:4,5; Joh 17:21-23; 2Co 6:16; Eph 3:17; 1Jo 3:24; 1Jo 4:12,15,16; Re 3:20

¹ tn Or “who chews.” On the alternation between ἐσθίω (esqiw, “eat,” v. 53) and τρώγω (trwgw, “eats,” vv. 54, 56, 58; “consumes,” v. 57) see the note on “eats” in v. 54.

² sn Resides in me, and I in him. Note how in John 6:54 eating Jesus’ flesh and drinking his blood produces eternal life and the promise of resurrection at the last day. Here the same process of eating Jesus’ flesh and drinking his blood leads to a relationship of mutual indwelling (resides in me, and I in him). This suggests strongly that for the author (and for Jesus) the concepts of ‘possessing eternal life’ and of ‘residing in Jesus’ are virtually interchangeable.
