Just another nerd.
My God (his son Jesus,actually), declared publicly that he was the son of God, that he would die on the cross, be buried, rise from the dead and, days later, ascend into heaven to rule beside father.
There were many witnesses who heard his predictions. And there were hundreds who witnessed his actual crucifixion, death, resurrection and ascension. Their written records of what they saw and heard survive today, and they are consistent with each other.
May you have ears to hear, and may God bless you in all things.
