Faith
The worst moment for the atheist is when he is really thankful, and has nobody to thank. (Dante Rossetti, 19th century British poet)
It may take more faith to be an atheist than to believe in a personal, almighty God. To the believer it seems really hard to understand how one could deny the existence of God with the evidence of nature pointing to a master creator and the vacuum in men’s hearts to find something noble outside of themselves. A searching mind can find help studying the Bible.
The heavens proclaim the glory of God. The skies display his craftsmanship. (Psalm 19:1)
