St. Paul, in his Epistle to the Romans, refers to those who receive βthe abundance of graceβ and βthe gift of righteousnessβ (Rom. 5:17) which God in love bestows upon all who trust in His Son for salvation.
The Bible declares that no man can ever stand uncondemned in the sight of God, the Judge of all, unless he receives righteousness as the gift of Godβs grace.
Quoting from the Psalms, the Apostle says in Romans 3:10; βIt is written, there is none righteous, no, not oneβ. This is why Paul pitied those who continued to go about βto establish their own righteousnessβ (Rom. 10:3). He knew that their struggle was utterly futile, that they needed to be saved (Rom. 10:1).
Let us thank God that the Lord Jesus Christ took the condemnation and judgment of our sins upon Himself at Calvary so that His righteousness might be imputed to us by grace through faith. Regarding Abrahamβs justification before God, the Apostle says: βWhat saith the Scripture? Abraham believed God, and it was counted unto him for righteousnessβ (Rom. 4:3).
Abrahamβs justification, of course, was based on the fact that Christ was to die for sin, but Christβs death is now past; it is an historical fact. Thus righteousness is now proclaimed through Christ and offered to all as a gift. βWhile we were yet sinners, Christ died for usβ (Rom. 5:8). βGod hath made Him to be sin for usβ¦that we might be made the righteousness of God in Himβ (II Cor. 5:21).
But we must receive this righteousness as a gift, for βto him that worketh not, but believeth on Him that justifieth the ungodly, HIS FAITH is counted for righteousnessβ (Rom.4:5). source
