I base my faith upon the Word of God. Does this man know the heart of man that he can make these claims? The word of God is all sufficient for sustaining one's faith. For any person to say it's not enough is borderline blasphemy, IMO.
He is someone that has not yet been saved by faith.
Lets see what their first Pope says
1Pe 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
1Pe 1:24 For all flesh [is] as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away:
1Pe 1:25 But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
Pray for this author that God open his eyes and ears to hear and believe .
