In a nutshell, the teaching of imputed righteousness from the eternal security view point is: a person once saved is holy and righteous without living holy and righteously. For people who believe in that false version of imputed righteousness, a Christian takes on Jesus' righteousness at the point of salvation and this righteous and holy standing before God can never be changed even by the most vile and heinous evils that could afterwards be committed. They also tell us sometimes: God can't see the Christian's sin. Instead, he only sees Jesus' righteousness, blood and grace, but never the sin! To them, Jesus' holiness and blamelessness is the Christian's forever holiness and blamelessness. That is their teaching of imputed righteousness, which is both demonic and lethal.

No, what Dan Corner is errantly teaching is demonic and lethal. Mr. Corner is foolishly saying that you cannot go to Heaven without works. That contradicts even the plainest teaching of the Scripture. ...
Romans 3:23-26, “For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.”Titus 3:5-7, “Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; Which he shed on us abundantly through Jesus Christ our Saviour; That being justified by his grace, we should be made heirs according to the hope of eternal life.
Romans 6:1, “What shall we say then? Shall we continue in sin, that grace may abound?”
“If you do not put a difference between justification wrought by the man Christ without and sanctification wrought by the Spirit of Christ within, you are not able to divide the Word aright; but contrariwise, you corrupt the Word of God, and cast stumbling blocks before the people.” —John Bunyan
