I would be happy with a few emails or even a text message or two.
Like the old joke-
“He doesn’t call! He doesn’t write!”
Dang!
We sent a boat; and then a BIGGER boat and then a HELICOPTER; but the flood victim kept saying he was waiting to be rescued!
But God DID write and He calls out to the whole world through the Holy Spirit, who convicts the world of sin, righteousness and judgment. In talking to unbelievers, I've heard more than once or twice the claim that if Jesus Christ appeared before them, then they would believe. However, Jesus said himself that such unbelief is a symptom of a stubborn and wicked heart and that even if someone were to come back from the dead and appear before them, they STILL would refuse to believe. For those who hang onto their rebellion against God, nothing will really convince them to change their minds. There needs to first be a softening of the heart towards God and a diligent, truthful, humble and repentant spirit that seeks after the truth in order for the light to get through.
“He doesn’t call! He doesn’t write!”
Jesus has already answered your joke. Proof is subjective, and evidence is objective. Neither I nor anyone else can convince another person of the veracity of the four Gospels, when that person has set his mind in concrete, and refuses to examine and accept solid evidence.
Simon Greenleaf, one of the principal founders of Harvard wrote the rules for what is acceptable evidence on which United States law is based.
Greenleaf's Treatise on the Law of Evidence, published in three volumes between 1842 and 1853, forms the basis for his study of the Gospels. Greenleaf came to the conclusion that the witnesses were reliable, and the resurrection of Jesus occurred. See his The Testimony of the Evangelists, Examined by the Rules of Evidence Administered in Courts of Justice.
