More on God's Promises and God's Law
In our previous meditation, we saw that God implements His plan of salvation by making and fulfilling promises. His plan is not contingent upon man's ability to perform acceptably before His holy law. To put it another way, the law of God (given hundreds of years after the promises to Abraham) does not replace those promises.
This raises a very important question: "What purpose then does thelaw serve?" If God's law did not cancel or rearrange His promises to Abraham, then why was it added? "It was added because oftransgressions." God wanted people to know that they had a major problem: sin. Man's sin needed to be clearly defined. "For by the law is the knowledge of sin" (Romans 3:20). The extent of sin would never be fully known apart from the law. "I would not have known sin except through the law" (Romans 7:7). Also, God wanted everyone in this world to know that they were accountable to Him for their transgressions. Thus, the law convicts the sinfulness of man, that "all the world may become guilty before God" (Romans 3:19).
This raises another important question. "Is the law then against thepromises of God?" The law does not replace God's promises, but does it work against His promises? "Certainly not!" The law of God and thepromises of God simply have different purposes (just as it is with law and grace). The law of God reveals the holiness that is inherent to the very character of God. At the same time, it describes the holy life that God wants His people to live. "You shall be holy, for I the LORD your God am holy" (Leviticus 19:2). The promises of God become the means by which man deals with his unholiness and accesses God's holiness. This is what true spiritual life is about: forgiveness of sinand a life of righteousness in Christ. This cannot come by law performance. "For if there had been a law given which could have given life, truly righteousness would have been by the law." Rather, the promise of life is entered into only by faith. "But the Scripture has confined all under sin, that the promise by faith in Jesus Christ might be given to those who believe."
