Overall well done and written, except for this technicality, which pertains to a false charge of contradiction by adversaries:
And the men which journeyed with him stood speechless, hearing a voice , but seeing no man. (Act 9:7)
And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou me? it is hard for thee to kick against the pricks. (Act 26:14)
And they that were with me saw indeed the light, and were afraid; but they heard not the voice of him that spake to me. (Act 22:9)
But the word for "voice" ("phōnē) can simply mean "sound" versus a the articulation, as in John 12:28-29:
Father, glorify thy name. Then came there a voice from heaven, saying, I have both glorified it, and will glorify it again. The people therefore, that stood by, and heard it, said that it thundered: others said, An angel spake to him.
Thus the men traveling with Paul fearfully heard a sound without an apparent source, but did not hear the words "Saul, Saul," etc).
And what we need is "ears to hear:" Deuteronomy 29:4 Ezekiel 12:2 Matthew 11:15 Matthew 13:9 Matthew 13:43 Mark 4:9 Mark 4:23 Mark 7:16 Luke 8:8 Luke 14:35
And Rev. 2:7 etc, cf. 1 Sam. 15:22 as well. Better hear the quiet voice, as Elijah, than be so distracted by assembly and/or missionary work that He has to thunder as in Rev 1:10:
"I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet, . . ."
Had Beloved John gotten distracted? Might he actually have been the messenger to the Ephesians?
