"Wolves" and "false prophets' who cast off their first irresistible faith:
1Tim 5:12 Having damnation, because they have cast off their first faith.
Strawman, no. "Wolves" and "false prophets' never had "irresistible faith" to begin with, they are pretenders like Judas.
Yet more projection. Are you saying the publican chose God instead of God choosing the publican; therefore, he must have saved himself.
Luke 18:13 And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner.
Another strawman. No, I am saying anyone who believes God; God chooses them to do so. Or in other words their belief/faith comes from and originates in God. Where do you think belief/faith originated from; God or man?
