Antony Flew passed away 8 April 2010. He was for many decades a prominent philosopher and apologist for atheism. In 2001 he converted to theism, but he never believed in the resurrection of Jesus Christ and His saving power from sin.
A simple affirmation in God or a supreme deity is not sufficient to save a man’s soul from the torments of hell. “You believe that God is one [and] you do well; [but] the demons also believe, and shudder” (James 2:19). To believe that God is one can be a mere intellectual assertion. To believe that He is, is to assent to a proposition even the demons acknowledge. Saving faith includes cognitive knowledge but goes beyond it to personal trust in His plan for salvation through His Son, the Lord Jesus Christ. It requires a regeneration of the inner man, becoming born-again by the Spirit of God: Jesus said, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God” (John 3:3).
If Antony Flew did not recognize his need for the atoning power of Christ’s death on the cross, then he is now, and will forever be, condemned to hell.
