Why are you (still) a Christian?

[Bucky Ball]

Prophesy is not prediction. Omen reading was forbidden. 
"Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft,"
Deeuteronomy 18:10

It was not a prophesy of Jesus. 
Isaiah was telling the King that HIS wife / consort was pregnant, and that they would win the war. 

Excellent, Bucky. Not only that but God doesn't see into the future like a fortune teller because the future doesn't exist. We can look into the past because it once existed but we can't look into the future. Fortune telling is either fake or demonic deception. God and demons can better see what could happen in the future than we can so they can deceive us - just like demons can more accurately recount the past and so deceive us into thinking spirits, that is ghosts or shades (shadows) are once living now dead humans.

Fascinating, isn't it?!

Let's see . . . what was I going to say? Oh, I know, case in point. At the trial of Jesus when they covered his head and slapped him they told him to prophecy to them who had done it. That didn't require seeing into the future. Prophecy means to proclaim, for example, something God can see will happen or will make happen. Like, for someone to say "I'm going to get ice cream" and then doing it, or "He's going to get ice cream." How did you know? "He always gets ice cream this time of day." Ezekiel prophesied to the wind. Ezekiel 37:9-10

ETA: Wait a minute, I forgot I have more to add.

There was no trial. Galilean peasants never got trials before Roman aristocrats. Reading the passions, they are very different, not even on the same day, one says he was silent one says he gave a long speech. They made it all up. Trouble-makers were summarily executed and tossed into a common grave. 
Some day, you really should take History 101. .
