John 6:40

6:40 For this is the will of my Father – for everyone who looks on the Son and believes in him to have eternal life, and I will raise him up ¹  at the last day.” ² 

John 6:54

6:54 The one who eats ³  my flesh and drinks my blood has eternal life, and I will raise him up on the last day. ⁴ 

¹ tn Or “resurrect him,” or “make him live again.”

² sn Notice that here the result (having eternal life and being raised up at the last day) is produced by looking on the Son and believing in him. Compare John 6:54 where the same result is produced by eating Jesus’ flesh and drinking his blood. This suggests that the phrase in 6:54 (eats my flesh and drinks my blood) is to be understood in terms of the phrase here (looks on the Son and believes in him).

³ tn Or “who chews”; Grk ὁ τρώγων (Jo trwgwn). The alternation between ἐσθίω (esqiw, “eat,” v. 53) and τρώγω (trwgw, “eats,” vv. 54, 56, 58; “consumes,” v. 57) may simply reflect a preference for one form over the other on the author’s part, rather than an attempt to express a slightly more graphic meaning. If there is a difference, however, the word used here (τρώγω) is the more graphic and vivid of the two (“gnaw” or “chew”).

⁴ sn Notice that here the result (has eternal life and I will raise him up at the last day) is produced by eating (Jesus’) flesh and drinking his blood. Compare John 6:40 where the same result is produced by “looking on the Son and believing in him.” This suggests that the phrase here (eats my flesh and drinks my blood) is to be understood by the phrase in 6:40 (looks on the Son and believes in him).
