sn The one who has the Son. The expression “to have the Son” in 5:12 means to “possess” him in the sense that he is present in the individual’s life (see 1 John 2:23 for the use of the Greek verb “to have” to indicate possession of a divine reality). From the parallel statement in 5:10a it is clear that believing in the Son and thus having God’s testimony in one’s self is the same as “having” the Son here in 5:12a. This is essentially identical to John 3:16: “that whoever believes in him should not perish but have eternal life.” In contrast, the negative statement in 5:12b reflects the author’s evaluation of the opponents: “the one who does not have the Son does not have (eternal) life.” The opponents, in spite of their claims to know God, do not possess (nor have they at any time possessed, cf. 2:19) eternal life.
