Justification is a foundational doctrine in Christian theology, referring to the act by which God declares a sinner to be righteous on the basis of faith in Jesus Christ. This concept is central to the teachings of the Apostle Paul and is pivotal in understanding the nature of salvation.

In the New Testament, justification is primarily discussed in the Pauline epistles. Romans 3:23-24 states, "for all have sinned and fall short of the glory of God, and are justified freely by His grace through the redemption that is in Christ Jesus." This passage highlights that justification is a gift of grace, not earned by human effort but granted through faith in the redemptive work of Christ.

The mechanism of justification is further explained in Romans 5:1 : "Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ." Here, faith is identified as the means by which individuals are justified, resulting in peace with God. This peace signifies a restored relationship between the believer and God, overcoming the alienation caused by sin.

Paul contrasts justification by faith with the works of the law in Galatians 2:16 : "know that a man is not justified by works of the law, but by faith in Jesus Christ. So we, too, have believed in Christ Jesus, that we may be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified." This underscores the belief that adherence to the law cannot achieve justification; rather, it is through faith in Christ alone.

The doctrine of justification also involves the imputation of Christ's righteousness to the believer. 2 Corinthians 5:21 states, "God made Him who knew no sin to be sin on our behalf, so that in Him we might become the righteousness of God." This exchange—Christ taking on the sin of humanity and believers receiving His righteousness—is central to the understanding of justification.

Inheritance

Inheritance in the biblical context refers to the spiritual and eternal blessings promised to believers as children of God. This concept is deeply rooted in both the Old and New Testaments, where it signifies the blessings and promises bestowed upon God's people.

In the Old Testament, inheritance often refers to the physical land promised to the descendants of Abraham, Isaac, and Jacob. For example, in Genesis 17:8 , God promises Abraham, "And to you and your descendants I will give the land of your sojourn—all the land of Canaan—as an eternal possession; and I will be their God." This inheritance of land is a tangible sign of God's covenant with Israel.

In the New Testament, the concept of inheritance takes on a spiritual dimension. Believers in Christ are described as heirs of God and co-heirs with Christ. Romans 8:17 states, "And if we are children, then we are heirs: heirs of God and co-heirs with Christ—if indeed we suffer with Him, so that we may also be glorified with Him." This inheritance includes eternal life, the kingdom of God, and the fullness of salvation.

Ephesians 1:13-14 further elaborates on this spiritual inheritance: "And in Him, having heard and believed the word of truth—the gospel of your salvation—you were sealed with the promised Holy Spirit, who is the pledge of our inheritance until the redemption of those who are God’s possession, to the praise of His glory." The Holy Spirit is described as a guarantee of the believer's inheritance, assuring them of their future redemption and eternal blessings.

The inheritance promised to believers is imperishable and eternal, as emphasized in 1 Peter 1:4 : "and into an inheritance that is imperishable, undefiled, and unfading, reserved in heaven for you." This inheritance is not subject to decay or loss, reflecting the eternal nature of God's promises.

In summary, the biblical concept of inheritance encompasses both the physical promises made to Israel and the spiritual blessings granted to believers in Christ, highlighting the continuity and fulfillment of God's covenantal promises throughout Scripture.
