I have often wondered how Christians give conflicting statements on the definition of a sinner! For instance when you commit sin! Does it make you a sinner? When you live a godly life does it make you righteous? The scriptures say our righteousness is like a filthy rag! For all have sinned and come short of the glory of God. Does it mean there's nothing like righteousness and we are all sinners before God! If Jesus died for our sins and his blood shed for our redemption paving a way to God in whom there's no unrighteousness how one correlates that scripture! The scripture says righteousness comes by faith Romans 4:3-5 (3) For what said the scripture Abraham believed God, and it was counted unto him for righteousness (4) Now to him that worketh is the reward no reckoned of Grace, but of debt (5) But to him that worketh not, but believeth on him that justifieth the ungodly his faith is counted for righteousness. It is important as a believer to know there's a difference in the definition of sin under the law and also under Grace! And Grace comes by faith! Romans 3:20 says… Therefore by the deed of the law there shall no flesh be justified in his sight: for by the law, is the knowledge of sin. But now the righteousness of God without the law is manifested being witnessed by the law and the prophets. It simply means the laws of Moses were given only for condemnation and it was never designed for our justification! Which means no matter your godly living and obedience to God you wouldn't still be justified and you will always be a sinner! But under grace it is your faith that makes you righteous, not your obedience or godly living, even when you sin it does not make you a sinner, that is why Romans 1:17 says ... For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
But to enjoy the grace, you must live by faith and to live by faith you must accept Jesus as your Lord and Saviour! You must confess openly and you must believe whole heartedly. So believers next time somebody comes and says to you “sinner” correct the person instantly that you are righteous by faith through Christ Jesus because the scripture Romans 3:24-26 says Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be 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 Christ! And Ephesians 2:5 says by grace we are saved!
