E. A. Rowell describes himself as the Atheist of atheists. He says:
My parents and other immediate relatives were proud of their unbelief. I was nourished on the vaunting skeptics of the ages.
But I observed the futile amazement with which every skeptic from Celsus to Wells stood around the cradle of the Christ. I wondered why this helpless Babe was thrust into the world at a time when Roman greed, Jewish hate, and Greek subtlety would combine to crush Him. And yet this most powerful, devastating combination ever known in history served only to advance the cause of the Infant who was born in a stable—the purest human being in the world born in the filthiest place in the world.
No unbeliever could tell me why His words are as charged with power today as they were nineteen hundred years ago. Nor could scoffers explain how those pierced hands pulled human monsters with gnarled souls out of a hell of iniquity and overnight transformed them into steadfast, glorious heroes who died in torturing flames, that others might know the love and mighty power of the Christ who had given peace to their souls.
No agnostic could make clear why seemingly immortal empires pass into oblivion, while the glory and power of the murdered Galilean are gathering beauty and momentum with every attack and every age.
Nor could any scoffer explain, as Jesus Himself so daringly foretold, why by telephone, airplane, and radio, by rail, horse, and foot, His words are piercing the densest forest, scaling the highest mountains, crossing the deepest seas and the widest deserts, making converts in every nation, kindred, tongue, and people on earth.
No doubter could tell me how this isolated Jew could utter words at once so simple that a child could understand them and so deep that the greatest thinkers cannot plumb their shining depths...
But I learned that the paradox was plain and the mystery solved when I accepted Him for what He claimed to be—the Son of God, come from heaven a Saviour of men, but above all, my own Saviour. I learned to thrill at the angel’s words: “Behold.... unto you is born this day... a Saviour, which is Christ the Lord.”
Are you an unbeliever who does not quite know why he/she does not believe? or you used to believe when you were a child but now as a grown-up you think this is rubbish. So, why don't you ask Jesus-Christ himself ? In Matthew 7, Jesus-Christ says:
7 ‘Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 8 For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened.
