因為父怎樣在自己有生命，就賜給他兒子也照樣在自己有生命。

5:26 “For just as the Father has life in himself, so also he has given to the Son to have life in himself” (ὥσπερ γὰρ ὁ πατὴρ ἔχει ζωὴν ἐν ἑαυτῷ, οὕτως καὶ τῷ υἱῷἔδωκεν ζωὴν ἔχειν ἐν ἑαυτῷ). The explanatory “for” (γὰρ) signals that Jesus is explaining the source and power behind the life that the Son provides. The restorative life the Son provides comes from the very life of God, both Father and Son. “Just as” (ὥσπερ) the Father has “life in himself” (ζωὴν ἐν ἑαυτῷ), so also does the Son, matching the “unseen” foretold by the prologue (1:4). “Life” is the possession of God, echoing a standard theme from the OT (Gen 2:7; Deut 30:20; Job 10:12; 33:4; Pss 16:11; 36:9). Life is functionally and ontologically so attached to God that it is simply “in him,” both the Father and the Son.

It is important to note that the Father “has given to the Son” (τῷ υἱῷ ἔδωκεν) to have life in himself. Such language is theologically intriguing, for while the Son is frequently in the Gospel dependent upon the Father, in regard to “life” he is also entirely and individually capable (cf. v. 21). This basic word—“life”—also includes some mystery. We are not told exactly what the term means, but what we are told is quite clear: “Life” is in the Son. Just as Jesus reveals the Father, so also does he make known and make possible life. All mystery regarding the divine and life itself finds their answer in Jesus, who incorporates them all in his flesh, through which he explains and imparts them to humanity.
