NASB: “Jesus said to them, ‘Truly, truly, I say to you, before Abraham was born I am’” (as in most trans.)
NWT: “Jesus said to them: ‘Most truly I say to you, Before Abraham came into existence, I have been.’”
Greek: εἶπεν αὐτοῖς Ἰησοῦς· ἀμὴν ἀμὴν λέγω ὑμῖν, πρὶν Ἀβραὰμ γενέσθαι ἐγὼ εἰμί (eipen autois Iēsous: amēn amēn legō humin, prin Abraam genesthai egō eimi).
That Jesus Christ, the Son of God, is truly God (YHWH) and truly man, is a main theme in John’s literature . This is especially seen by the response of the Jews in places such as John 5:59; 8:59; and 10:33. Notwithstanding, non-Christian unitarian groups (such as Muslims, JWs, Oneness Pentecostals et al.) reject this. Their rejection is chiefly based on a pre-committed theology and not exegesis of the text.
Jesus declared in John 8:24: “For if you should not believe that I am [egō eimi] you will perish in your sins” (lit. trans.). Although most translations add either a predicated clause or the pronoun “he” after “I am”, the fact is there is no pronoun (i.e., no supplied predicate) contained after egō eimi (“I am”) in any Greek manuscript of John 8:24 or after Jesus’ other affirmations of being the “I am” as in Mark 6:50; John 8:28, 58; 13:19; 18:5, 6, and 8. . An added predicate is a decision made by the translator. Hence, these particular occurrences in John of Jesus’ claim to be the “I am” are not the same as statements in which contain a clear and stated predicate, such as, for example, “I am the door, the shepherd, the bread,” etc. Whereas the several “I am” statements exampled in John 8, 13:19, and 18:5, 6, 8 (and Mark 6:50) have no stated predicate in the Greek, but rather the “I am” stands alone–which would be an absolute claim to deity. Thus, the burden of proof would rest on the one attempting to show otherwise.
As shown below, John 8:58 contextually and syntactically (esp. in light of the verb contrast) asserts an absolute unequivocal claim of deity made by Christ, which was clearly understood by the Jews in the next verse. However, whether or not the “I am” statements in the other passages are contextually unpredicated, that is, “I am the eternal God” claims, the deity of the Son is well established in the entire content of John’s literature (John 1:18; 5:17-18; 10:30; 20:28; 1 John 5:20; Rev. 1:7-8, 17; 22:13 et al.).
Hebrew, Ani Hu
To understand the full theological significance of the phrase egō eimi, the OT background must first be considered.
The Hebrew phrase, ani hu (“I [am] He”), which was translated egō eimi in the Septuagint (LXX), was an exclusive and recurring title for YHWH alone (cf. Deut. 32:39; Isa. 41:4; 43:10; 46:4; 48:12)—which the Jews clearly understood (cf. John 8:59). Again, Jesus’ claim to be the “I am” was not only seen in John 8:58 (as many assume), but note the marked progression starting in 8:24, then, vv. 28, 58; 13:19; 18:5, 6, and 8. It is when we examine all the “I am” statements do we see the consequence of His claim.
When Jesus declared He was the “I am” at John 18:5, 6, and 8, we read that the “fearless” Romans soldiers “fell to the ground.” What would cause Roman soldiers to fall to the ground? So powerful were Jesus’ divine pronouncements that it caused His enemies to shudder to the ground. Even when Jesus was being arrested at perhaps one of the lowest points of His life on earth, He still retained total sovereignty over His enemies.
So strong was Jesus’ affirmation of deity in John 8:58 that the JWs’ Bible the NWT mistranslated the present active indicative verb, eimi (“am”) turning it into a past tense: “I have been.” From this, the JW’s argue that Jesus was not claiming to be deity (“I am”), but rather He was claiming to be “older” than Abraham was (as Michael the archangel), which incited the Jews to want to kill Him. However, what immediately refutes this false notion is:
1) Simply, the Greek text contains the present indicative verb eimi (“am”) and not any kind of past tense. In 1969, the Watchtower Bible and Tract Society (WT) published a Greek Interlinear called, The Kingdom Interlinear Translation of the Greek Scriptures (KIT) and a revised ed. in 1985. The KIT is a Greek NT with English equivalents under each Greek word and the NWT on the side margins. What is interesting is that the Greek is unchanged, only the NWT is altered from the Greek.
For example, notice the photocopy of John 8:58-59 from the KIT in which you can see the unaltered Greek phrase egō eimi (“I am”) and the NWT’s altered reading “I have been,” on the side:
This clearly shows that the NWT purposely altered the Greek NT text, from the present “I am” to a past “I have been” (as if Jesus was merely saying that He is older than Abraham) to fit the distinctive theology of the WT.
2) Even more, throughout the years, the WT has offered at least three reasons as to why the present tense verb eimi (“am”) should be translated as a past action (“have been”). First, in the 1950 ed. of the NWT, there is a footnote referring to the “I have been” rendering, which states: “I have been— ἐγώ εἰμι [egō eimi] . . . properly rendered in the perfect indefinite tense. . . .” (p. 312).
This sounds legitimate to one who is not familiar with Greek, however, there is no such tense as a “perfect indefinite” in biblical Greek. The WT made up a phony tense. Some have defended the WT’s explanation saying that “perfect indefinite” refers to the English, not the Greek. But we are not aware of a single official WT source that states this.
Then, the WT argued that the verb eimi was a “perfect indicative.” Now, there is a perfect indicative in Greek, however, the verb eimi takes no such form. And currently, the WT asserts that eimi is a “historical present” explaining that “The verb ei·mi’, at John 8:58, is evidently in the historical present, as Jesus was speaking about himself in relation to Abraham’s past” (emphasis added). Thus, the JWs see Jesus as merely claiming that He pre-existed Abraham, which, according to the JWs, enraged the Jews to the point of wanting to kill Him (cf. v. 59). This assertion, however, is flawed both grammatically and contextually.
First, a historical present tense occurs primarily in narrative literature and only in third person. In this context, Jesus was arguing with the Jews—He was not narrating. Secondly, the equative verb eimi is not used as a historical present. As the recognized Greek scholar, Daniel Wallace, points out:
If this is a historical present, it is apparently the only historical present in the NT that uses the equative verb eimi. The burden of proof, therefore, lies with the one who sees eimi as ever being used as a historical present. . . If this is a historical present, it is apparently the only historical present in the NT that is in other than third person.
The weight against the historical present view is massive. The reason for these various assertions of eimi postulated by the WT throughout the years (viz. the phony perfect indefinite; perfect indicative, and historical present) is, of course, obvious. If Jesus’ divine statements of being the “I am,” stand unmodified, then, Jesus made some astonishing and unambiguous claims of being the eternal God (as with John 5:17 and 10:27-30), which clearly show the WT to be a false religion in need of salvation.
 Although Roman Catholicism holds to the deity of Christ, they reject His work as being sufficient, the very ground of justification (esp. seen in Rome’s view of Purgatory). Since Paul states that it is “His [God’s] doing” that we are in Christ, who became to us “righteousness, and sanctification, and redemption” (1 Cor. 1:30), Rome clearly embraces a “different” Jesus than that of holy Scripture, a Jesus, that did not, alone, become the believers’ righteousness.
 Ean gar mē pisteusēte hoti egō eimi apothaneisthe en tais hamartiais humōn.
 For example, the pre-2011 NIV has a bracketed clause after “I am” that reads: “the one I claim to be.”
 Although the non-predicated divine declaration, “I am,” John 8:58 is accepted universally as a divine claim in biblical scholarship, not all scholars hold 8:24 in the same light as reflected in many translations. However, some translations (e.g., ISV ; NAB) do see the phrase at 8:24 as unpredicted: “I am.”
The Aramaic Bible in Plain English (2010) reads: “I said to you that you shall die in your sins, for unless you shall believe that I AM THE LIVING GOD, you shall die in your sins” (caps theirs). Also see Vincent’s Word Studies, where 8:24, 28, 58 and 13:19 are seen as a “solemn expression” of Jesus’ “absolute divine being” (cf. Mark 6:50).
 Some connect Exodus 3:14 with John 8:58. However, as mentioned, the LXX rendering of Exodus 3:14 is not an exact equivalence: Egō eimi ho ōn (“I am the Being” or “Existing One”). Though there is a solid connection between Jesus’ divine claim in John 8:58 and Exodus 3:14 (both provide same meaning: I am the Eternal one. Also note the articular participle, ὁ ὢν (ho ōn, “the one who is/being always”) in the LXX of Exodus 3:14. When contextually warranted, as in 3:14, the phrase indicates timeless existence – “who is always existing.” The phrase is applied to the Father in Revelation 1:4 and 4:8 and applied to the Son and John 1:18 denoting the Son’s eternal existence: “No one has seen God at any time; the only the unique God who is [ho ōn, i.e., “the One who is/being always”] in the bosom of the Father, He has explained Him.” Also applied to the incarnate Son in Romans 9:5 with the same sematic: “Whose are the fathers, and from whom is the Christ according to the flesh, who is [ho ōn, i.e., “the One who is/being always”] over all, God blessed forever. Amen.” The phrase also appears in Revelation 1:8. Although referential identity is not clear (Father or Son), verse 7 clearly refers to the Son, which seems to correlate naturally with verse 8.
As pointed out above, the full theological impact of Jesus’ divine declarative should be linked to the Hebrew phrase ani hu (“I [am] He”), which was rendered by the LXX as egō eimi. Again, the unpredicted egō eimi was a divine title used exclusively by YHWH (e.g., Deut. 32:39; Isa. 41:4; 43:10; 46:4). Unlike Elohim (“God”), the title egō eimi was never applied to men or angels, but to YHWH alone: “See now that I am [egō eimi], and there is no god except Me” (Deut. 32:29, LXX).
 The WT is the organization to which the JWs belong and submit.
