Tit 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; 6 Which he shed on us abundantly through Jesus Christ our Savior; 7 That being justified by his grace, we should be made heirs according to the hope of eternal life. Look what Jesus did for us on the cross when we receive Him as Lord and Savior.
We have been Justified through His sacrifice of the cross. Justification is a legal term that we are made righteous. Justification means we are declared righteous in God’s sight—not by human merit, but by His grace.
Christ’s righteousness is so imputed to believers that their justification is not merely the act of a sovereign dispensing with law but the act of a judge declaring the law to be satisfied. Charles Hodge
