His fame was limited when He was crucified.

Across a chasm of eighteen hundred years, Jesus Christ makes a demand which is beyond all others difficult to satisfy; He asks for that which a philosopher may often seek in vain at the hands of his friends, or a father of his children, or a bride of her spouse, or a man of his brother. He asks for the human heart; He will have it entirely to Himself. He demands it unconditionally; and forthwith His demand is granted. Wonderful! In defiance of time and space, the soul of man, with all its powers and faculties, becomes an annexation to the empire of Christ. All who sincerely believe in Him, experience that remarkable, supernatural love toward Him. This phenomenon is unaccountable; it is altogether beyond the scope of man's creative powers. Time, the great destroyer, is powerless to extinguish this sacred flame; time can neither exhaust its strength nor put a limit to its range. This is it, which strikes me most; I have often thought of it. This it is which proves to me quite convincingly the Divinity of Jesus Christ.

I know men; and I tell you that Jesus Christ is no mere man. Between Him and every person in the world there is no possible term of comparison. Alexander, Caesar, Charlemagne, and I have founded empires. But on what did we rest the creations of our genius? Upon force. Jesus Christ founded His empire upon love; and at this hour millions of men would die for him.
