Come on Winman, you've been doing this long enough to know the verses they alway appeal to.
John 6 (the passage where the gospel hasn't even been revealed to the world, by which to draw/enable men to respond)
Romans 8 (the passage that speaks of man's inability to submit to the law, which they translate to mean that man can't submit in faith to the one who fulfilled the law in our stead)
1 Cor 2 (the passage that speaks of the need for spiritual discernment concerning the "deep things of God" that even the carnal believers in Corinth could not receive, yet they apply it to man's total inability to believe the gospel (a spiritual message given by inspiration so that we can understand the mysteries of the kingdom).
Which ones am I missing?
maybe Apostle paul in Romans, where NONE are either rightious/good, NONE seek after God, ALL have turned away from Him?
Or that sinful men everywhere knows God exists from nature, yet refuse to acknowledge Him, and bow down to "gods" of their own making!
