And then what is Ananias, chopped liver?
The risen Christ told Ananias that Paul was his chosen instrument.
How many accounts from first-hand witnesses to these events do we have?
How many accounts of firsthand
witnesses do we have every time God spoke the Law to Moses from the Holy Place?
(Lev 1:1, 4:1, 5:14, 6:1, 8, 19, 24, 7:22, 28, 8:1, 12:1, 14:1, 16:1, 2, 17:1, 18:1, 19:1, 20:1, 21:1, 16, 22:1, 17, 26, 23:1, 9, 23, 26, 33, 24:1, 27:1:1; Nu 1:1, 4:21, 5:1, 11, 6:1, 22, 8:1, 5, 23, 9:1, 10:1, 11:16, 23, 13:1, 15:1, 17, 37, 17:1, 18:25, 21:8, 34, 25:4, 10, 16, 26:52, 27:12, 18, 28:1, 31:1, 25, 34:1, 16, etc., etc., etc.)
Or spoke to Balaam (Nu 22:9, 12, 20, 23:16), etc.?
Does that keep you from believing that God did speak what is recorded of him?
This is misunderstanding, misusing and employing a double standard,
regarding the Biblical
requirement of two or three witnesses,
which applies only to testimony regarding wrongdoing (Nu 35:30; Dt 17:6, 19:15; Mt 18:16; 1Tim 5:19; Heb 10:28).
And with your wrong
requirement of two or three witnesses
to the event of God speaking, you set at naught 99% of Leviticus, Numbers, the Prophets, etc., because there were no witnesses to it.
Likewise, your wrong requirement sets at naught Paul's call by the risen Christ to be an apostle (Gal 1:1; 1Ti 1:1), because there were no witnesses to that either.
And then there's the double standard of applying your wrong requirement to NT events, but not to OT events, such as God speaking to Balaam.
Do you believe God spoke to Balaam? There were no witnesses.
This is a grasping at straws of human rationale and double standards, with no Biblical foundation for your rejection of most of the NT Word of God.
Good luck with that.
