OSAS is a lie from the pit of hell!
From the Old to the New Testament the message remains the same. God does not change and thus it is the same regarding His plan of salvation. Again, When a righteous man doth turn from his righteousness, and commit iniquity, and I lay a stumblingblock before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand.  Nevertheless if thou warn the righteous man , that the righteous sin not, and he doth not sin, he shall surely live, because he is warned; also thou hast delivered thy soul. Ezekiel 3:20-21 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.  For it had been better for them not to have known the way of righteousness, than, after they have known it , to turn from the holy commandment delivered unto them.  But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire. 2 Peter 2:20-22 OSAS is a lie from the pit of hell! Even God's chosen people do not get a free pass! Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. Matthew 21:43 They must repent and submit to God through obedience to Jesus Christ as much as anyone else does.
