Perhaps you think your witness doesn’t matter

Blaise Pascal, one of history’s greatest scientists, was not converted through his scientific queries. Rather, when the scientist’s carriage was once suspended on a bridge and the man was hanging between life and death, the only thing Pascal could think of was the Christian conviction of his sister and her witness of Christ.Pascal was the inventor of the barometer. He was brilliant as a philosophical scientist. But the one thing that kept piercing his heart till he surrendered his all to Christ was the Christian witness of his sister.
