When Robert Ingersoll the notorious skeptic, was in his heyday, two college students went to hear him lecture. As they walked down the street after the lecture, one said to the other, “Well, I guess he knocked the props out from under Christianity, didn’t he?”
The other said, “No, I don’t think he did. Ingersoll did not explain my mother’s life, and until he can explain my mother’s life, I will stand by my mother’s God.
– James S. Hewett
The Bible has a great deal to say about the walk of the believer proving the existence of God.
For at one time you were darkness, but now you are light in the Lord. Walk as children of light
Whoever walks with the wise becomes wise, but the companion of fools will suffer harm. Disaster pursues sinners, but the righteous are rewarded with good.
Give it some thought and if you can’t prove it to others, at least walk it.
