We are judged by the work of Christ on the cross, given to us by God alone.
Christ's work saves us. Christ's obedience saves us. Christ's sacrifice saves us.
"For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous." -- Romans 5:19
When the Christian dies and is judged, God has promised us He will forgive our sins because Christ took upon Himself to pay for those sins, enabling us to stand acquitted and blameless before God's perfect justice.
For those not in Christ there is His wrath. For those in Christ, there is only mercy.
"Now to him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness... Now it was not written for his sake alone, that it was imputed to him; But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; Who was delivered for our offences, and was raised again for our justification. " -- Romans 4:4-5,23-25 "Thou shalt not be affrighted at them: for the LORD thy God is among you, a mighty God and terrible." -- Deut. 7:21
***We are judged by the work of Christ on the cross***
How can you be judged by what someone else has done? None of Reformed theology makes a whit of sense. Holy Spirit frogmarching the undeserved into Heaven. Legions of the undeserved shambling off to hell.
Calvinists call the holy profane and the profane holy. You people are really special.
