The the books of the old testament were written 100's and in some cases thousands of years before the New Testament and the birth of Christ.
The Old Testament Contains almost 350 prophesies predicting the coming of Christ.
Christ crucified Propehsized in (Psalm 22:16)
Fulfilling: Jesus was crucified (John 19:17, 18)
Just fullfilling that prophecy
1 x 104 or 1 in 10,000
8 of them are considered 'major.' He fulfilled all 344 of them all but the odds of fulfilling just the first 8 are as so:
1 in 10,000,000,000,000,000,000,000,000,000
Happy Birthday Jesus.
