The OSAS people mock God claiming if one sows to the flesh (sin) they do not reap corruption as the Lord teaches in His Word (Gal 6:7,8) and they make a mockery of what Jesus teaches in John 15 when He said those IN Him who do not bear fruit are cut off from the vine (taken away).
I'd hate to be one of the OSAS folks on judgement day. It's gonna be brutal for these people
Romans 2:7-11
To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
For there is no respect of persons with God.
