ἵνα ... τὸν ἱμάντα

The verb is governed by the ἵνα clause and expresses the action John says he is not worthy to perform. It is framed as a contemplated or potential action, not as a completed event.

It functions as the verb of the purpose clause, describing the humble act of untying the strap that John disclaims for himself.

It is not a statement that the action happened, and it does not by itself define the object beyond the nearby phrase about the sandal strap.

High: The subjunctive belongs to John's confession of unworthiness before the coming one.

Aorist active subjunctive in a purpose or complement clause. names the humble action John says he is not worthy to perform. Attached to the clause about untying the sandal strap. Governed by John's statement that he is not worthy. The clause is framed by unworthiness, not by a completed action.

What act does John say he is not worthy to perform? He says he is not worthy to untie the coming one's sandal strap.

Direct: The subjunctive supports to untie or that I might untie in context.

The aorist should not be reduced to a once-for-all claim. The subjunctive is governed by the clause, not by a completed event. The first-person form belongs to John's confession and should not be generalized.

Aorist subjunctive proves timing by itself: The clause expresses a potential act within John's unworthiness statement; context governs timing and force.

The witness reads λύσω in John 1:27, within the phrase οὐκ εἰμὶ ἄξιος ἵνα λύσω αὐτοῦ τὸν ἱμάντα τοῦ ὑποδήματος.

The lemma λύω commonly means to loosen, untie, release, or destroy, but the local context favors the concrete sense of untying.

The subjunctive after ἵνα presents the action as intended, contemplated, or potential. Here it serves John's humble refusal, not a report that he actually unties the sandal strap.

The verse stresses the greatness of the coming one and John's unworthiness even for the most menial service toward him.

This fits the wider Gospel witness to Jesus' superiority and John's role as witness, preparing readers to see Christ as the one who comes first in honor.

For readers and teachers, the form communicates humility and deference by placing the untying of the strap in the sphere of what John is not fit to do.

Do not derive a claim that the tense alone proves timing, or that the form itself creates a theological doctrine apart from the sentence.
