Well, the first issue is that it's impossible to be 100% sure that it's God, and the rest.
I'm not convinced of that, so here is your opportunity to convince me.
Did Moses not know with 1000% certainty when God gave him that proof... among others?
(Exodus 4:1-5)
1 However, Moses answered: “But suppose they do not believe me and do not listen to my voice, for they will say, ‘Jehovah did not appear to you.’” 2 Then Jehovah said to him: “What is that in your hand?” He answered: “A rod.” 3 He said: “Throw it on the ground.” So he threw it on the ground, and it became a serpent; and Moses fled from it. 4 Jehovah now said to Moses: “Reach out your hand and seize it by the tail.” So he reached out and seized it, and it became a rod in his hand. 5 God then said: “This is so that they may believe that Jehovah the God of their forefathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.”
Put yourself in the scene.
Did Israel have any reason for doubt at all, when they "
went through the midst of the sea on dry ground, while the waters formed a wall on their right hand and on their left. . ."? (Exodus 14:22)
Put yourself in the scene.
Did the disciples know with 100% certainty, after they left that mountain?
(2 Peter 1:16-21)
16 No, it was not by following artfully contrived false stories that we made known to you the power and presence of our Lord Jesus Christ, but rather, we were eyewitnesses of his magnificence. 17 For he received from God the Father honor and glory when words such as these were conveyed to him by the magnificent glory: “This is my Son, my beloved, whom I myself have approved.” 18 Yes, these words we heard coming from heaven while we were with him in the holy mountain. 19 So we have the prophetic word made more sure, and you are doing well in paying attention to it as to a lamp shining in a dark place (until day dawns and a daystar rises) in your hearts. 20 For you know this first, that no prophecy of Scripture springs from any private interpretation. 21 For prophecy was at no time brought by man’s will, but men spoke from God as they were moved by holy spirit.
Put yourself in the scene.
Did Stephen think for a fraction of a second that he was hallucinating?
(Acts 7:55, 56)
55 But he, being full of holy spirit, gazed into heaven and caught sight of God’s glory and of Jesus standing at God’s right hand, 56 and he said: “Look! I see the heavens opened up and the Son of man standing at God’s right hand.”
Place yourself in Stephen's position.
If you were in Moses' position, or you crossed the Red sea, walking on dry land, or were on the mountain witnessing the transfiguration... would you be 100% certain... or would you say, you can't be sure? What would you need to convince you? Why do you doubt?
This is what I was drawing to your attention, in
Post #270, when I said to you...
I think you may be looking at the situation only through your eyes. However, if that is, lacking faith, then it would be hard to see anything else.
Nothing would convince you, or change your mind. It would be equivalent to convincing a man who had scales on his eyes,
so thick as to make Saul's blindness obsolete, that it was daytime.
It would be unreasonable to put Abraham, or Moses, or any of the aforementioned characters in the same boat as yourself.
Because you doubt, does not mean others doubt.
Because you may be blind to what they see, does not mean they are blind too.
Abraham knew with 100% certainty. He knew God spoke to him, the only thing he needed to do, was have faith in God, and the promises he had not yet seen.
But let's assume a 99% on all factors - that it was God, and they were guilty. I'd probably still ask for the reasoning behind it, but assuming that was forthcoming and 99% convincing, I might well do so, yes.
Okay, so 99%... Convince me that Abraham did not have this. See
Post #270, again.
